Testing system provides RF flexibility
Engineers are successfully using the GP-22050 to emulate the control interface between the transceiver and its array of front-end RFICs.
A cellular components supplier uses Byte Paradigm's GP-22050 for evaluation, characterisation and manual bench testing of RF chips RF chips such as power amplifiers, switches and LNAs (low-noise amplifiers) are moving away from GPIO (general-purpose I/O) control in favor of a digital interface standard

The GP-22050 Base is a bidirectional PC-based module that functions as a pattern generator, logic analyser/data logger and JTAG protocol generator.
USB module boosts instrument data throughput
The GP-22050 is a multipurpose PC-based USB 2.0 module used to stream data between a PC and an embedded or remote system.
These chips are controlled by the 'transceiver' or baseband processor in mobile phones.
When these RFIC silicon products have returned from the fab, they must be set in different operating modes during the testing and characterisation process.
Engineers are successfully using the GP-22050 to emulate the control interface between the transceiver and its array of front-end RFICs.
They also use the GP-22050 when supplying samples to customers, providing the PC-based hardware tool to them for evaluation.
The company's cellular products configuration and control interface varies from product to product.
The products generally use two or three wires, and the company is likely to consolidate to two-wire interfaces in the future.
These interfaces don't always use the same protocol standard, which derives from the SPI (standard peripheral interface) protocol.
Hence, testing the chips requires a great deal of flexibility.
C DLL was provided, which is a necessity when working with nonstandard protocols.
The company has developed its own VB (Visual Basic) internal application that use the C/C++ APIs provided with Byte Paradigm GP-22050 device. Request a free brochure from Byte Paradigm ...
