NXP Semiconductors OM7801/BGU7003/868

Overview

OM7801/BGU7003/868 from NXP Semiconductors is a fully assembled evaluation board for the BGU7003 silicon germanium low-noise amplifier MMIC, optimized for 868 MHz ISM band operation at 2.8 V supply with 5 mA quiescent current and integrated input/output matching networks.

For engineers reviewing the OM7801/BGU7003/868 datasheet, OM7801/BGU7003/868 pinout, OM7801/BGU7003/868 application, or OM7801/BGU7003/868 equivalent, this board enables rapid RF performance validation-including power-on/off settling time measurement-without external biasing or matching components.

Technical Context

The OM7801/BGU7003/868 implements a fixed-gain, single-stage LNA evaluation platform centered on the BGU7003 MMIC, which operates across 863–870 MHz with 19 dB small-signal gain and 1.4 dB noise figure. It integrates discrete decoupling capacitors and microstrip-based impedance-matching networks tuned specifically for 868 MHz.

No external DC bias circuitry or RF tuning elements are required: the board provides direct SMA access to RF input and output ports, and supports only 2.8 V DC supply via dedicated test point or edge connector, aligning with the BGU7003's specified operating voltage range.

FAQ

What is the primary function of the OM7801/BGU7003/868 evaluation board?

The OM7801/BGU7003/868 evaluation board is a ready-to-use RF platform for characterizing the BGU7003 low-noise amplifier MMIC at 868 MHz. It provides full signal path matching, DC biasing, and SMA interfaces-enabling immediate measurement of gain, noise figure, and settling times without additional circuitry. The OM7801/BGU7003/868 requires only a 2.8 V DC source and standard RF test equipment.

Does the OM7801/BGU7003/868 support operation outside the 868 MHz ISM band?

The OM7801/BGU7003/868 is specifically optimized for 868 MHz (863–870 MHz) with fixed microstrip matching networks. While the underlying BGU7003 MMIC operates over a wider frequency range, the OM7801/BGU7003/868 board's performance-especially gain flatness and noise figure-is not characterized or guaranteed outside this band. For other frequencies, redesign of matching networks is required.

How is power delivered to the OM7801/BGU7003/868 board?

Power is supplied to the OM7801/BGU7003/868 board via a dedicated 2.8 V DC test point or edge connector; no onboard voltage regulation is included. The board draws approximately 5 mA, matching the BGU7003's quiescent current specification. Users must ensure clean, well-decoupled 2.8 V supply to avoid RF performance degradation on the OM7801/BGU7003/868.

Can the OM7801/BGU7003/868 be used to measure power-on and power-off settling times?

Yes-the OM7801/BGU7003/868 explicitly supports evaluation of power-on settling time (t_on) and power-off settling time (t_off) as stated in its official user manual (UM10517). These measurements are enabled by the board's direct DC enable path and absence of slow-start circuitry, allowing precise timing analysis of the BGU7003's transient response on the OM7801/BGU7003/868.

Is the OM7801/BGU7003/868 supplied with documentation and design files?

Yes-the OM7801/BGU7003/868 ships with the UM10517 user manual (v1.0, dated 2011-12-14), which includes schematic diagrams, bill of materials, layout details, and measurement procedures. No PCB Gerber files or simulation models are provided with the OM7801/BGU7003/868, but the manual contains all necessary information for functional validation and integration reference.
