NXP Semiconductors OM7815/BGU7008/FE,598

Overview

OM7815/BGU7008/FE from NXP is a fully assembled GPS front-end evaluation board built around the BGU7008 SiGe:C low-noise amplifier MMIC, featuring two integrated SAW filters, input series inductor, decoupling capacitor, and SMA connectors for RF test equipment interfacing. It operates from 1.5 V to 2.85 V, draws ~4.7 mA, and supports GPS/GLONASS/Galileo band evaluation.

For engineers reviewing the OM7815/BGU7008/FE datasheet, OM7815/BGU7008/FE pinout, OM7815/BGU7008/FE application, or OM7815/BGU7008/FE equivalent, this board enables rapid characterization of power-on/off settling times (t_on/t_off), noise figure, gain flatness, and out-of-band rejection in GPS front-end designs.

Technical Context

The OM7815/BGU7008/FE implements a complete single-stage GPS front-end signal path: RF input → SAW filter → BGU7008 LNA → SAW filter → RF output. The BGU7008 delivers 17.5 dB small-signal gain and 1.3 dB noise figure at 1.575 GHz, with input/output matched to 50 Ω via integrated matching networks.

Power supply is routed through a dedicated 1.5–2.85 V bias network with on-board decoupling; DC blocking capacitors isolate RF ports while preserving DC bias integrity. The board's layout maintains controlled-impedance microstrip traces and grounded coplanar waveguide sections to preserve S-parameter accuracy up to 2 GHz.

FAQ

What is the primary function of the OM7815/BGU7008/FE evaluation board?

The OM7815/BGU7008/FE evaluation board is designed to accelerate testing and validation of the BGU7008 low-noise amplifier in GPS, GLONASS, and Galileo receiver front-ends. It integrates all necessary passive components, dual SAW filters, and SMA interfaces so engineers can immediately measure gain, noise figure, linearity, and settling behavior without custom PCB development. The OM7815/BGU7008/FE eliminates RF matching uncertainty and provides a reference design for production-level GNSS front-end modules.

Does the OM7815/BGU7008/FE support power-on/off timing evaluation?

Yes, the OM7815/BGU7008/FE explicitly supports measurement of power-on settling time (t_on) and power-off settling time (t_off) per its documented features. These parameters are critical for GPS receivers implementing duty-cycled LNA operation to reduce average current draw. The OM7815/BGU7008/FE's clean bias network and minimal parasitic capacitance enable accurate oscilloscope-based timing analysis of the BGU7008's enable/disable response.

What RF frequency bands does the OM7815/BGU7008/FE cover?

The OM7815/BGU7008/FE is optimized for the GPS L1 band (1575.42 MHz), GLONASS G1 band (1602 MHz), and Galileo E1 band (1575.42 MHz). Its dual SAW filters and BGU7008's specified 1.3 dB noise figure and 17.5 dB gain at 1.575 GHz confirm coverage across these overlapping GNSS bands. The board's microstrip layout and SMA connectors maintain performance integrity up to 2 GHz, supporting adjacent-band interference testing.

Can the OM7815/BGU7008/FE be used with standard RF test equipment?

Yes, the OM7815/BGU7008/FE includes two SMA female connectors-one for RF input and one for RF output-enabling direct connection to vector network analyzers, spectrum analyzers, and signal generators without adapters or impedance-matching fixtures. All RF paths are 50 Ω matched, and DC blocking capacitors prevent bias leakage into test instruments. This makes the OM7815/BGU7008/FE compatible with standard lab-grade RF characterization workflows.

Is the OM7815/BGU7008/FE supplied with documentation and sample code?

The OM7815/BGU7008/FE ships with an evaluation board user manual and access to the BGU7008 datasheet, application notes, and recommended PCB layout guidelines via NXP's official website. While it does not include firmware or sample code-since it is an analog RF evaluation platform-the OM7815/BGU7008/FE documentation provides measurement procedures, S-parameter data, and biasing recommendations essential for integrating the BGU7008 into final designs.
