NXP Semiconductors OM7805/BGU7008,598

Overview

OM7805/BGU7008 from NXP is a fully assembled GPS/GNSS low-noise amplifier evaluation board built around the BGU7008 SiGe:C MMIC LNA, operating from 1.5 V to 2.85 V with 4.7 mA supply current, and featuring SMA input/output connectors for RF test equipment interfacing in GNSS front-end validation.

For engineers reviewing the OM7805/BGU7008 datasheet, OM7805/BGU7008 pinout, OM7805/BGU7008 application, or OM7805/BGU7008 equivalent, this board enables rapid characterization of power-on/off settling times (t_on, t_off), gain flatness, noise figure, and input/output match across GPS (1575.42 MHz), GLONASS, and Galileo bands without external biasing or matching networks.

Technical Context

The OM7805/BGU7008 implements a single-stage 5-pin BGU7008 MMIC configured in common-emitter topology with on-board DC blocking and decoupling, optimized for 1.575 GHz operation. It integrates a series input inductor and ceramic decoupling capacitor to establish stable bias and broadband matching.

Designed for direct connection to vector network analyzers and spectrum analyzers, the board supports S-parameter measurement, gain compression (P1dB), and noise figure evaluation under real-world supply conditions - all using only the onboard BGU7008 and two SMA ports.

FAQ

What is the primary function of the OM7805/BGU7008 evaluation board?

The OM7805/BGU7008 evaluation board is a dedicated test platform for the BGU7008 SiGe:C low-noise amplifier, enabling direct RF performance measurement - including gain, noise figure, input/output match, and power-on/off settling behavior - without external circuitry. The OM7805/BGU7008 simplifies GNSS LNA validation in lab and pre-production environments.

Does the OM7805/BGU7008 require external biasing or matching components?

No. The OM7805/BGU7008 is fully assembled with the BGU7008 MMIC, an input series inductor, and a decoupling capacitor - no external biasing, matching, or filtering components are needed. Engineers can connect RF test equipment directly via the two SMA connectors and begin characterization immediately using the OM7805/BGU7008.

Which GNSS frequency bands does the OM7805/BGU7008 support?

The OM7805/BGU7008 is optimized for GPS L1 (1575.42 MHz), GLONASS G1 (1602 MHz), and Galileo E1 (1575.42 MHz) bands. Its layout and component selection ensure proper impedance matching and minimal loss across these frequencies, making the OM7805/BGU7008 suitable for multi-constellation GNSS receiver evaluation.

Can the OM7805/BGU7008 be used to measure power-on and power-off settling times?

Yes. The OM7805/BGU7008 explicitly supports evaluation of power-on settling time (t_on) and power-off settling time (t_off) as stated in its official user manual (UM10488). This capability is critical for verifying fast-switching behavior in battery-powered GNSS receivers, and the OM7805/BGU7008 delivers repeatable timing measurements under defined supply conditions.

Is the OM7805/BGU7008 supplied with documentation and firmware?

The OM7805/BGU7008 ships with the UM10488 user manual (v1.0, dated 2011-06-30), which details board layout, test setup, and measurement procedures. No firmware is included - the OM7805/BGU7008 is a passive RF evaluation platform with no microcontroller or programmable logic; all functionality is inherent to the BGU7008 MMIC and board-level RF design.
