Overview

Description

The F2914EVBI is a fully populated evaluation board which allows the customer to easily evaluate the F2914 RF switch. 

“Thru” calibration connectors are conveniently located on the eval board to simplify the calibration process prior to making any RF measurements. Each RF port (RF1, RF2, RF3, and RF4) can be connected to RFC by applying the correct control logic voltage to the V1, V2 and V3 control pins as outlined in the F2914 datasheet. The Vssext feature gives the customer the option to supply an external negative voltage to the Vssext header pin to shut down the internal charge pump for low spur operation.

Features

  • RF connectors for RFC and each of the four RF ports
  • The F2914EVkit has a number of control features available
    • Refer to the EVkit Application Circuit , EVkit Picture and Applications information in the F2914 datasheet to properly connect to and control the evaluation board features.
    • All bias and logic controls are applied to the appropriate pins of the pin header located on the evaluation board
  • “Thru” port connectors are located on the evaluation board for easy calibration prior to making RF measurements

IDT RF Product Benefits Overview

Hello, my name is Dan Terlep. I'm a Product Definer in IDT's RF group. What I'm going to talk about are some of the customer benefits of IDT's technical innovations used in RF products. These are unique innovations that differentiate our products from competitive parts. Up to 10x improvement in RF performance can be obtained when using these devices in your designs. This technology is highly desired by equipment vendors and is protected by patents.

Glitch-free technology essentially eliminates the transient overshoot that can occur during mSv attenuation state transitions of standard digital step attenuators. Flat-noise technology maintains near constant noise performance [inaudible 00:00:48] reduced in our variable gain amplifiers, thus optimizing system level signal-to-noise performance. Zero-distortion technology practically eliminates intermodulation distortion in our RF mixers and amplifiers, enhancing the system's quality of service. Kz refers to constant impedance technology, which has implemented a new line of RF switches that allows 'hot switching' in TDD systems.

Additional benefits of using IDT's RF solutions include: enable screen networks with minimal power consumption; allow scaling from macrocells to microcells using the same device with reduced voltage, reduced current, or both; improves reliability by replacing gallium arsenite with silicon; improves data throughput by optimizing signal-to-noise performance and overall dynamic range; tolerates higher operating temperature than competitive devices.

Note that IDT's RF cards are used by all major cellular 3G and 4G equipment manufacturers for systems deployed all over the world. IDT's advanced RF portfolio using these technologies includes: mixers, digital step attenuators, RF switches, variable gain amplifiers, and modulators. These are silicon monolithic devices offered in QFN packages.

In summary, IDT's RF portfolio replaces gallium arsenite parts, results in higher reliability, provides better signal-to-noise performance, faster settling times, eliminates glitching and third-order intermodulation distortion, reduces DC power consumption, and operates at higher temperatures.
