Qualcomm’s 10 Gigabit 5G Modem-RF System for Mobile Broadband and Industrial IoT

Posted on 22 February, 20213 August, 2021 by Abhishek Jadhav

When it comes to the system on the chip in your smartphone, tablet, or even the wireless modem, Qualcomm has dominated the market for quite a few years now. A few days back, the company announced World’s first 10 gigabit 5G modem-RF system that will increase the 5G support in mobile broadband, compute, XR, industrial IoT, 5G private networks, and fixed wireless access. This becomes the fourth generation Qualcomm Snapdragon X65 getting the first 3GPP release with 16 modem-to-antenna solution.

The manufacturer added more to its announcement with the release of the SnapdragonX62 5G Modem-RF system, a modem-to-antenna solution designed for mainstream adoption of mobile broadband applications. The X65 5G Modem-RF system is designed with an upgradable architecture that allows the adoption of new features while reducing the total cost of ownership. Qualcomm showcases the QTM545 fourth-generation mmWave antenna module that increases the mobile mmWave coverage area and improves power efficiency.

The innovation does not stop here, the X65 also has the world’s first AI antenna tuning technology that has enhanced the tuning capabilities leading to faster data speeds, better coverage, and longer battery life. When it comes to power saving, Qualcomm has also been at the forefront. To add to this, X65 gets Qualcomm’s 5G PowerSave 2.0 that comes with new power-saving technologies defined in 3GPP Release 16.

“The 5G transition presents the biggest opportunity for Qualcomm as mobile technology is poised to benefit virtually every industry,” said Cristiano Amon, president and CEO-elect, Qualcomm Incorporated. “We are reaching a significant milestone with the Snapdragon X65 5G Modem-RF System, unleashing connectivity up to 10 Gigabits per second and support for the latest 5G specifications that will play a critical role in enabling new 5G use cases not only for redefined premium smartphone experiences, but also opening a new realm of possibilities for 5G expansion across mobile broadband, compute, XR, industrial IoT, 5G private networks and fixed wireless access.”

If you are still wondering ‘why’ it is important and significant to launch the product in the broader aspect of the industry. With the release of 10 Gigabit 5G, it is necessary to have a 5G Modem-RF System that will bring a new set of features to premium smartphones. The company explains by saying:

“With multi-gigabit 5G enabled by the Snapdragon X65 5G Modem-RF System, consumers will have access to fiber-like browsing speeds and low-latency, delivered wirelessly over 5G for the next generation of connected applications and experiences, including cloud- and edge-based computing, highly responsive multiplayer gaming, rich entertainment, immersive 360-degree video, and instant apps.”

For those interested in the products, Snapdragon X65 and Snapdragon X62 are expected in the commercial devices by late 2021.

Arduino Nano- Switching ON/OFF Appliances Using Infra-Red Remote (Two Channel)

The project presented here is a two-channel infrared remote ON/OFF switch that can be used to control home appliances, Lights, Fans, Water Pumps, Aquarium pumps, Ovens, Heaters, etc. This open-source project contains 2 x SSR (Solid State Relay), Arduino Nano, and TSOP1838 infrared receiver, keeping safety in mind, optically isolated SSR (Solid State Relay) is used to have isolation between high voltage AC circuitry and Arduino Nano. The operation of the circuit is pretty simple, TSOP1838/TSOP38238 IR Sensor receives the infrared signal from IR remote, Arduino Nano decodes the IR signal which is connected to digital pin D2 and provides latch outputs on digital pins D5, and D6 in respect to IR code received from IR remote. These two digital outputs D5, D6 drive the SSR using 2 x BC847 BJT transistors. CPC1998J optically isolated solid-state relays from IXYS Integrated Circuits drive the AC loads. We have tested this board with 500W/230V AC lamps, however, the load capacity of SSR is 20A. A snubber circuit is provided across the SSR-Traic which helps driving inductive loads. Heat-sink on SSR is not required for loads up to 5A, but for higher load, it is advisable to mount a heatsink on SSR.

Components Functions: U2 & U3 SSR Relay AC Load driver, U4 TSOP1838/TSOP38238 IR Sensor, R1 & R4 Current limiting resistor for SSR LED, Q1 & Q2 LED Driver of SSR, D1 & D2 Protection Diode for SSR LED, C1 & C2 + R1 & R5 Snubber Circuit for AC Inductive Load.
Connections: CN2 AC Input 110V-220V AC, CN1 Load, CN3 Load, CN4 5V DC Supply If Arduino Nano USB power is not available, CN5 DC Power (Optional) 7V to 12V if USB/5V power is not available.
Power Supply DC: The Arduino Nano can be powered via the Mini-B USB connection, 7-12V unregulated external power supply (CN5), or 5V regulated external power supply (CN4).

CPC1998J is an AC Solid State Switch utilizing dual power SCR outputs. This device also includes zero-cross turn-on circuitry and is specified with an 800VP blocking voltage. Tightly controlled zero-cross circuitry ensures low noise switching of AC loads by minimizing the generation of transients. The optically coupled input and output circuits provide exceptional noise immunity and 2500Vrms of isolation between the control and the output. As a result, the CPC1998J is well suited for industrial environments where electromagnetic interference would disrupt the operation of plant facility communications and control systems

Arduino Pin configurations: Digital Pin D2 TSOP1838 Infra-Red Receiver, Digital Pin D5 and D5 outputs

Note 1: This board can accommodate other SSR like S216S02 from Sharp, CPC1998J from IXYS or KSD215AC3 available from http://www.cosmo-ic.com

Note 2: This project also can be used for many other applications that require 2 x SSR, Optional U5 connector is provided to interface analog/digital device or sensor

INA190-Q1, 40V, bi-directional, ultra-precise current sense amplifier

Posted on 20 February, 202120 February, 2021 by mixos

The INA190-Q1 is an automotive, low-power, voltage-output, current-shunt monitor (also called a current-sense amplifier). This device is commonly used for monitoring systems directly connected to an automotive 12-V battery. The INA190-Q1 can sense drops across shunts at common-mode voltages from –0.2 V to +40 V, independent of the supply voltage. In addition, the input pins have an absolute maximum voltage of 42 V.

Features

Low Supply Voltage, VVS: 1.7V to 5.5V
Wide Common-Mode Voltage: –0.2V to +40V
Low Shutdown Current: 100nA (Max)
Low Input Bias Currents: 500pA (Typ) (Enables Microamp Current Measurement)
Low Offset Voltage, VOS: ±15 µV (Max)
Accuracy:
- Gain Error: ±0.2% (A1 Devices)
- Offset Drift: 0.13µV/°C (Max)
- Gain Drift: 5ppm/°C (Max)
Gain Options:
- INA190A1: 25V/V
- INA190A2: 50 V/V
- INA190A3: 100V/V
- INA190A4: 200V/V
- INA190A5: 500V/V
Quiescent Current: 50µA at 25°C (Typ)
Package: 1.8mm x 1.4mm UQFN-10

The low input bias current of the device permits the use of larger current-sense resistors, thus providing accurate current measurements in the microamp range. The low offset voltage of the zero-drift architecture extends the dynamic range of the current measurement. This feature allows for smaller sense resistors with lower power loss, while still providing accurate current measurements.

The INA190-Q1 operates from a single 1.7-V to 5.5-V power supply and draws a maximum of 65 µA of supply current. Five fixed gain options are available: 25 V/V, 50 V/V, 100 V/V, 200 V/V, or 500 V/V. The device is specified over the operating temperature range of –40°C to +125°C, and offered in an SC70 package.
