NXP Semiconductors OM7922/BGA7204,598

Overview

OM7922/BGA7204 from NXP Semiconductors is a customer evaluation kit for the BGA7204 - a 400 MHz to 2750 MHz high-linearity variable gain amplifier used in RF front-end signal conditioning. The kit includes a fully populated RF evaluation board, USB interface board, BGA7204 samples, calibration tracks for de-embedding, and PC-based SPI control software for setting attenuation states, reading temperature, reprogramming gain curves, and power-down control.

For engineers reviewing the OM7922/BGA7204 datasheet, OM7922/BGA7204 pinout, OM7922/BGA7204 application, or OM7922/BGA7204 equivalent, this evaluation kit enables rapid functional validation of the BGA7204's RF performance, SPI programmability, thermal monitoring, and gain curve customization in wireless infrastructure prototyping environments.

Technical Context

The OM7922/BGA7204 kit implements a complete hardware-software evaluation platform centered on the BGA7204 IC, which integrates a digitally controlled variable gain amplifier with integrated temperature sensor and nonvolatile gain curve memory. Its USB interface board bridges PC-hosted software to the BGA7204's 4-wire SPI interface, supporting real-time register writes and readbacks including gain index, power-down bit, and die temperature.

RF evaluation board layout includes calibrated 50 Ω transmission lines, RF calibration tracks for S-parameter de-embedding, and on-board biasing circuitry enabling operation from USB-supplied 5 V only - no external power supply required for basic functionality.

FAQ

What is the OM7922/BGA7204 used for?

The OM7922/BGA7204 is an evaluation kit for the BGA7204 variable gain amplifier, enabling engineers to characterize its RF performance across 400–2750 MHz, validate SPI-controlled gain settings, monitor on-die temperature, and reprogram gain curves. It is not a production component but a development tool for wireless infrastructure design.

Does the OM7922/BGA7204 require external power supplies?

No - the OM7922/BGA7204 evaluation kit operates entirely from a standard USB 2.0 port delivering 5 V. Both the USB interface board and RF evaluation board are powered through the USB connector, eliminating need for external DC supplies during basic evaluation of the BGA7204.

What software is included with the OM7922/BGA7204?

The OM7922/BGA7204 includes PC-based evaluation software on a USB flash drive that provides plug-and-play SPI control of the BGA7204 without driver installation. Functions include setting attenuation states, reading die temperature, reprogramming the internal gain curve, and activating power-down mode.

Can the OM7922/BGA7204 be used for S-parameter measurements?

Yes - the OM7922/BGA7204 RF evaluation board includes dedicated calibration tracks adjacent to the BGA7204 mounting site, enabling precise de-embedding of PCB parasitics using a vector network analyzer. This allows accurate extraction of the BGA7204's true S-parameters.

Is the OM7922/BGA7204 compatible with other NXP RF evaluation kits?

The OM7922/BGA7204 uses a proprietary USB interface board and software stack specific to the BGA7204's SPI register map and feature set. It is not interoperable with evaluation kits for other NXP RF devices such as BGU700x or BGU8xx series due to differences in control protocol, pin mapping, and calibration structure.
