NXP Semiconductors OM7806/BGU7007,598

Overview

OM7806/BGU7007,598 from NXP Semiconductors is a fully assembled GPS front-end evaluation board built around the BGU7007 GPS low-noise amplifier, two Murata SAFEA1G57KE0F00 SAW band-pass filters, a 5.6 nH input matching inductor, and decoupling capacitor. It delivers 16.7 dB gain, 1.7 dB noise figure, and >90 dBc cellular TX rejection at 1850 MHz, targeting RF performance validation in mobile handset GPS receiver designs.

For engineers reviewing the OM7806/BGU7007,598 datasheet, OM7806/BGU7007,598 pinout, OM7806/BGU7007,598 application, or OM7806/BGU7007,598 equivalent, this evaluation board enables rapid characterization of GPS LNA linearity under jamming, noise figure stability, gain compression thresholds, and SAW filter integration - all with SMA RF I/O, DC bias header, and jumper-controlled enable logic.

Technical Context

The OM7806/BGU7007,598 implements a complete GPS front-end signal chain: RF input passes through a pre-filter SAW, then into the BGU7007 LNA (1575.42 MHz internally matched, AC-coupled I/O), followed by a post-filter SAW before RF output. Bias is supplied via 1.5–2.85 V single supply, with enable control routed through jumper JU1 to Ven.

It supports critical GPS coexistence testing: out-of-band IIP3 measurement using dual-tone jammers at 1713.42 MHz and 1851.42 MHz; 1 dB gain compression assessment under 850 MHz and 1850 MHz cellular TX interference; and noise figure degradation analysis under jamming - all validated per AN11101 Rev. 1.

FAQ

What is the primary function of the OM7806/BGU7007,598 evaluation board?

The OM7806/BGU7007,598 evaluation board is a ready-to-use GPS front-end test platform centered on the BGU7007 low-noise amplifier. It integrates two SAW band-pass filters, input matching inductor, decoupling capacitor, and SMA RF connectors to enable immediate RF characterization - including gain, noise figure, linearity under jamming, and TX rejection - without external circuitry. The OM7806/BGU7007,598 simplifies validation of GPS receiver sensitivity in cellular coexistence environments.

Does the OM7806/BGU7007,598 include the BGU7007 IC?

Yes, the OM7806/BGU7007,598 is a fully assembled evaluation board that includes the BGU7007 GPS low-noise amplifier as its core active component. The BGU7007 is mounted in its 1×1.45 mm package with integrated temperature-stabilized biasing and enable control. All supporting components - Murata SAW filters, 5.6 nH inductor, and decoupling capacitor - are pre-soldered, making the OM7806/BGU7007,598 a turnkey solution for RF performance testing.

What RF test equipment is required to operate the OM7806/BGU7007,598?

To operate the OM7806/BGU7007,598, you need a DC power supply (1.5–2.85 V, ≤30 mA), two RF signal generators (for dual-tone jammer testing at 1713.42 MHz and 1851.42 MHz), and an RF spectrum analyzer covering ≥6 GHz. A network analyzer is recommended for S-parameter and gain measurements, while a noise figure analyzer with 15 dB noise source is advised for accurate NF evaluation. All connections use standard SMA interfaces on the OM7806/BGU7007,598 board.

Can the OM7806/BGU7007,598 be used to evaluate alternative SAW filters?

Yes, the OM7806/BGU7007,598 layout supports drop-in replacement of the Murata SAFEA1G57KE0F00 SAW filters with other GPS-band SAWs sharing the same 1.05×1.35 mm footprint - including EPCOS 9444, Murata SAFA1G57KH0F00, and Fujitsu FAR-F6KA-1G5754-L4AA. Proper grounding per supplier guidelines is essential to maintain >90 dBc TX rejection; the OM7806/BGU7007,598 PCB design follows these recommendations with dedicated ground vias for each SAW pin.

What is the role of jumper JU1 on the OM7806/BGU7007,598 board?

Jumper JU1 on the OM7806/BGU7007,598 connects the BGU7007's Ven (enable) pin either to Vcc (for always-on operation) or to a separate control voltage (for logic-level enable/disable sequencing). This allows users to verify the BGU7007's <1 µA shutdown current and fast 0.9–1.4 µs power settling time - critical for power-gated GPS architectures. The OM7806/BGU7007,598 documentation confirms JU1 placement directly controls Ven functionality without requiring solder modification.
