Product details
Overview
OM7624/BGU7005FE,5 from NXP Semiconductors is a SiGe:C monolithic microwave integrated circuit (MMIC) low-noise amplifier optimized for GNSS L1-band reception (1559–1610 MHz) in space-constrained mobile devices. It delivers 16.5 dB gain, 0.85 dB noise figure, −11 dBm input 1-dB compression point at 1.8 V, and operates from 1.5 V to 3.1 V with 4.5 mA supply current. Its adaptive bias enables robust performance under cellular jamming conditions.
For engineers reviewing the OM7624/BGU7005FE,5 datasheet, OM7624/BGU7005FE,5 pinout, OM7624/BGU7005FE,5 application, or OM7624/BGU7005FE,5 equivalent, key selection criteria include GNSS LNA linearity under coexistence interference, ultra-low noise figure across temperature, minimal external component count (one inductor + one capacitor), and compatibility with 1 mm × 1.45 mm XSON6 (SOT886) PCB layouts.
Technical Context
The BGU7005 employs a self-biasing architecture with integrated temperature-stabilized DC biasing, eliminating need for external bias networks. Its RF_IN and RF_OUT are internally AC-coupled, enabling seamless integration into 50 Ω front-end chains without blocking capacitors.
It features dynamic current scaling: under high jamming (e.g., −20 dBm GSM burst), bias current increases temporarily to maintain sensitivity, while retaining <1 μA shutdown current in power-down mode via ENABLE pin control. The 110 GHz fT SiGe:C process ensures stable gain and noise performance across −40 °C to +85 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LNA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QM11012 | 0.95 dB NF, 15.8 dB gain, 1.1–3.3 V supply, same 6-pin 1.0×1.45 mm package | Optimized for GPS-only (1575.42 MHz) vs. full GNSS L1 band; lower jamming resilience | Preferred when cost-sensitive GPS-only designs tolerate 0.1 dB NF penalty and lack cellular coexistence requirements |
| Skyworks SKY65168-396LF | 1.1 dB NF, 17.2 dB gain, 1.6–3.3 V, 6-pin 1.0×1.5 mm QFN | Higher gain but wider bandwidth (1550–1650 MHz); no adaptive jamming mode | Selected for wideband GNSS+SBAS applications where maximum gain outweighs jamming immunity needs |

FAQ
What is the recommended input matching network for OM7624/BGU7005FE,5?
The OM7624/BGU7005FE,5 requires only a single 5.6 nH high-Q inductor (e.g., Murata LQW15A) between RF_IN and the antenna port to achieve 50 Ω input match across 1559–1610 MHz. No series/shunt capacitor is needed due to internal DC blocking and optimized transistor input impedance. This simplifies layout and reduces component count versus traditional LNA designs.
Does OM7624/BGU7005FE,5 support power-down functionality?
Yes, OM7624/BGU7005FE,5 includes an ENABLE pin (Pin 5) that places the device in ultra-low-power shutdown mode (<1 μA ICC) when driven to ≤0.35 V. Pulling ENABLE ≥0.8 V activates normal operation. This feature enables precise power gating in multi-mode GNSS receivers to meet stringent system-level power budgets.
How does OM7624/BGU7005FE,5 handle cellular jamming signals?
OM7624/BGU7005FE,5 dynamically increases its bias current during high-power jamming events (e.g., −20 dBm GSM burst at 850/1850 MHz), preserving gain and noise figure without external intervention. At 25 °C, NF remains ≤1.5 dB and gain stays ≥17.5 dB under −20 dBm jamming - a key differentiator for coexistence in modern smartphones.
What is the thermal resistance and maximum junction temperature of OM7624/BGU7005FE,5?
The OM7624/BGU7005FE,5 has a thermal resistance Rth(j-sp) of 225 K/W from junction to solder point. Its absolute maximum junction temperature is 150 °C. Under typical 4.5 mA / 1.8 V operation (8.1 mW dissipation), junction-to-ambient rise is <2°C on standard 2-layer FR4 with 20 mm² copper pour - enabling use in sealed, fanless handheld enclosures.
Is OM7624/BGU7005FE,5 compatible with common GNSS SAW filters?
Yes, OM7624/BGU7005FE,5 is designed for direct interface with industry-standard GPS SAW filters such as Murata SAFEA1G57KE0F00 and TDK EPCOS B9444. Its 50 Ω matched RF_OUT and 20 dB output return loss ensure minimal insertion loss and reflection-induced ripple when cascaded with these filters in GPS front-end configurations.
