NXP Semiconductors OM7814/BGU7004/FE,598

Overview

OM7814/BGU7004/FE from NXP is a fully assembled GPS front-end evaluation board built around the BGU7004 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 in handheld and portable navigation devices.

For engineers reviewing the OM7814/BGU7004/FE datasheet, OM7814/BGU7004/FE pinout, OM7814/BGU7004/FE application, or OM7814/BGU7004/FE equivalent, this board enables rapid characterization of BGU7004 power-on/off settling times (t_on, t_off), noise figure, gain flatness, and out-of-band rejection in real-world GPS front-end configurations.

Technical Context

The OM7814/BGU7004/FE implements a complete single-stage GPS LNA signal path with matched 50 Ω input/output impedance, centered at 1.575 GHz (GPS L1), and includes dual SAW filters for image and out-of-band suppression. The BGU7004 IC on board delivers 17.5 dB small-signal gain and 0.8 dB noise figure at 1.575 GHz under 1.8 V/4.7 mA bias.

This board supports DC-coupled enable/disable control for power sequencing validation and provides direct access to the BGU7004's RF_IN, RF_OUT, VCC, and GND terminals via solder pads and SMA interfaces-enabling both bench-level RF performance verification and system-level integration testing.

FAQ

What is the primary function of the OM7814/BGU7004/FE evaluation board?

The OM7814/BGU7004/FE evaluation board is a ready-to-use hardware platform for characterizing the BGU7004 low-noise amplifier in GPS/GNSS front-end applications. It integrates all necessary passive components-including two SAW filters, matching inductor, and decoupling capacitor-so engineers can immediately evaluate RF gain, noise figure, linearity, and power-on/off settling behavior without custom PCB design. The OM7814/BGU7004/FE eliminates prototyping delays for GNSS receiver development.

Does the OM7814/BGU7004/FE support GLONASS and Galileo frequency bands?

Yes, the OM7814/BGU7004/FE supports GLONASS and Galileo alongside GPS because the BGU7004 IC has broadband operation from 1.5 GHz to 1.65 GHz, and the integrated SAW filters are specified for GPS L1 (1575.42 MHz) with sufficient adjacent-band rejection. The OM7814/BGU7004/FE has been validated for multi-constellation GNSS front-end evaluation in smartphones and PNDs per NXP UM10490.

What power supply requirements does the OM7814/BGU7004/FE have?

The OM7814/BGU7004/FE requires a single DC supply between 1.5 V and 2.85 V, with typical operation at 1.8 V drawing approximately 4.7 mA. This matches standard low-voltage rails used in portable GNSS receivers. The OM7814/BGU7004/FE does not include onboard voltage regulation-users must supply clean, well-decoupled DC power to the VCC test point.

Can the OM7814/BGU7004/FE be used to measure power-on and power-off settling times?

Yes, the OM7814/BGU7004/FE explicitly supports evaluation of power-on settling time (t_on) and power-off settling time (t_off) as stated in its official features list. These parameters are critical for GPS receiver duty-cycling and fast acquisition. The OM7814/BGU7004/FE provides direct access to the BGU7004's enable node and RF output for oscilloscope-based transient measurement.

Is the OM7814/BGU7004/FE supplied with documentation and user guidance?

Yes, the OM7814/BGU7004/FE ships with UM10490 (v.1.0), the official user manual published by NXP on 2011-07-04. This document details board layout, component placement, measurement setup, S-parameter data, and recommended test procedures. All documentation for the OM7814/BGU7004/FE is available for download from NXP's product page.
