NXP Semiconductors OM7802/BGU7003/CMMB,598

Overview

OM7802/BGU7003/CMMB,598 from NXP Semiconductors is an evaluation board featuring the BGU7003 SiGe MMIC low-noise amplifier optimized for Chinese Mobile Multimedia Broadcasting (CMMB) reception in the 400 MHz to 800 MHz band. It delivers 19.5 dB power gain, 1.2 dB noise figure at 600 MHz, and −19.7 dBm input P1dB compression, enabling high-sensitivity front-end design in portable CMMB receivers.

For engineers reviewing the OM7802/BGU7003/CMMB,598 datasheet, OM7802/BGU7003/CMMB,598 pinout, OM7802/BGU7003/CMMB,598 application, or OM7802/BGU7003/CMMB,598 equivalent, this board provides a fully assembled, SMA-connected reference platform with verified RF performance, bias control, and layout guidance for rapid CMMB LNA integration and validation.

Technical Context

The OM7802/BGU7003/CMMB,598 implements the BGU7003 as a single-stage wideband LNA with temperature-stabilized internal biasing and logic-controlled power-down (0.4 µA standby). Input and output matching networks are externally designed on FR4 PCB using Murata 0402 components, targeting optimal noise figure and return loss across 400–800 MHz.

It operates from a 2.5 V supply, draws ~5 mA quiescent current, and integrates DC blocking (100 pF), LF decoupling (0.1 µF), and precision RF matching (22 nH/15 nH inductors, 10 pF/1.0 pF capacitors) - all validated per AN11097 Rev. 01 test data including Smith chart impedance plots and stability analysis (K-factor >1 up to 10 GHz).

FAQ

What is the primary function of the OM7802/BGU7003/CMMB,598 evaluation board?

The OM7802/BGU7003/CMMB,598 evaluation board is a fully assembled RF platform built around the BGU7003 SiGe MMIC to demonstrate and validate low-noise amplification for Chinese Mobile Multimedia Broadcasting (CMMB) reception between 400 MHz and 800 MHz. It provides measured performance data, layout guidelines, and ready-to-test SMA interfaces - all documented in NXP Application Note AN11097.

Does the OM7802/BGU7003/CMMB,598 include the BGU7003 IC?

Yes, the OM7802/BGU7003/CMMB,598 evaluation board includes the BGU7003 IC pre-mounted and fully integrated into the CMMB-optimized matching network. The board is shipped fully assembled with Murata 0402 passive components, SMA RF connectors, and a 3-pin DC header for bias control - as confirmed in the Bill of Materials (Table 1) of AN11097.

What supply voltage and current does the OM7802/BGU7003/CMMB,598 require?

The OM7802/BGU7003/CMMB,598 is characterized and tested at 2.5 V supply voltage, drawing approximately 5 mA quiescent current under normal operation. Its enable pin supports logic-level power-down mode, reducing current consumption to just 0.4 µA - a key feature for battery-powered CMMB receivers detailed in Section 2 of AN11097.

Can the OM7802/BGU7003/CMMB,598 be used outside the CMMB band?

While optimized for 400–800 MHz CMMB operation, the OM7802/BGU7003/CMMB,598 leverages the wideband BGU7003 MMIC, which supports LNA applications up to 6 GHz (e.g., GPS, satellite radio). However, its input/output matching network is fixed for CMMB; use outside this band requires redesign per AN11097's guidance on external matching flexibility.

Where can I find the schematic and layout files for the OM7802/BGU7003/CMMB,598?

The schematic diagram (Figure 3), PCB layout (Figure 4), and material stack (Figure 5) for the OM7802/BGU7003/CMMB,598 are published in NXP Application Note AN11097 Rev. 01. These include component footprints, controlled-impedance routing recommendations, grounding practices, and FR4 dielectric specifications (εr = 4.6–4.9) - all essential for replicating or adapting the design.
