Product details
Overview
OM7925/BGU7051,598 from NXP Semiconductors is a SiGe:C-based low-noise high-linearity RF amplifier designed as a 0.5–1.5 GHz LNA for wireless infrastructure front-ends. It delivers 21.0 dB associated gain, 0.65 dB noise figure, and +33 dBm output IP3 at 900 MHz under 3.3 V/65 mA operation, with internal 50 Ω matching eliminating external tuning components.
For engineers reviewing the OM7925/BGU7051,598 datasheet, OM7925/BGU7051,598 pinout, OM7925/BGU7051,598 application, or OM7925/BGU7051,598 equivalent, this device supports rapid integration into macrocell base station receive paths, small-cell remote radio units, and broadband repeater LNAs where ultra-low noise and high linearity are critical in constrained PCB space.
Technical Context
The BGU7051 employs a fully integrated SiGe:C bipolar transistor architecture enabling unconditional stability (K > 1 across 0–25 GHz) and high fT of 110 GHz. Its internal 50 Ω input/output matching eliminates external impedance transformers, reducing bill-of-materials and layout sensitivity.
It operates from a single 3.3 V supply with dual VCC pins (VCC1, VCC2) and four dedicated GND terminals to minimize ground inductance and maintain RF isolation. ESD protection per HBM (4 kV) and CDM (2 kV) standards ensures robust handling during assembly and field operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise Figure | 0.65 dB typical at 900 MHz - enables detection of weak signals in dense interference environments |
| Output IP3 | +33 dBm typical at 900 MHz - suppresses intermodulation distortion in multi-carrier LTE/FDD systems |
| Associated Gain | 21.0 dB typical at 900 MHz - provides sufficient signal lift before ADC or mixer stages without cascading amplifiers |
| Supply Current | 65 mA typical at 3.3 V - balances power efficiency with RF performance for thermally constrained modules |
| Operating Frequency | 0.5–1.5 GHz - covers primary bands for GSM, UMTS, LTE Band 5/8/20/28, and TDD-LTE deployments |
| Input/Output Return Loss | 24.5 dB / 18 dB typical at 900 MHz - ensures minimal reflection-induced gain ripple and VSWR < 1.15 |
| Thermal Resistance | 26 K/W junction-to-solder point - supports reliable operation up to +85 °C ambient in sealed enclosures |
Pinout & Package
OM7925/BGU7051,598 is housed in an HVSON10 (SOT650-1) thermally enhanced leadless package measuring 3.0 × 3.0 × 0.85 mm³ with exposed thermal pad. The 10-terminal layout supports low-inductance grounding and dual supply routing for optimal RF stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| n.c. | Not connected | Pins 1 and 10 are electrically isolated - no routing or soldering required |
| VCC1 | Supply voltage | Primary bias rail; requires local 100 pF decoupling adjacent to pin 2 |
| GND | Ground | Pins 3, 5, 6, 8 provide low-impedance RF return path; must connect directly to solid ground plane |
| RF_IN | RF input | Differential-capable single-ended port; internally matched to 50 Ω - no external matching network needed |
| RF_OUT | RF output | Single-ended 50 Ω output; maintains high reverse isolation (>26 dB) to prevent LO leakage coupling |
| VCC2 | Supply voltage | Secondary bias rail; independent decoupling (100 pF) required at pin 9 to suppress supply noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| SiGe:C process technology | 110 GHz fT enables wideband linearity and sub-0.7 dB NF below 1.5 GHz |
| Unconditional stability | K-factor > 1 from DC to 25 GHz - eliminates need for external stabilization networks |
| ESD protection on all terminals | HBM 4 kV / CDM 2 kV - withstands standard handling and board-level ESD events without derating |
| Moisture Sensitivity Level 1 | Non-bake requirement prior to reflow - compatible with standard J-STD-020 assembly flow |
| Internal 50 Ω matching | Eliminates discrete matching components - reduces BOM count and layout sensitivity across frequency band |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise high-linearity amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QPL9057 | Wider bandwidth (0.6–2.7 GHz), higher NF (0.75 dB @ 900 MHz), same 3.3 V supply but 75 mA typical current | Preferred for multi-band 5G NR FR1 designs requiring coverage beyond 1.5 GHz | Select QPL9057 when extending frequency range above 1.5 GHz is required; OM7925/BGU7051,598 remains optimal for cost-sensitive 0.5–1.5 GHz infrastructure. |
| Skyworks SKY67151-396LF | Higher gain (24.5 dB), slightly higher NF (0.7 dB), 5 V supply, larger 4 × 4 mm QFN package | Used in higher-power BTS applications where 5 V rails are already present and PCB area is less constrained | Choose SKY67151-396LF only if existing 5 V infrastructure exists and thermal design accommodates higher dissipation; OM7925/BGU7051,598 offers superior NF/power trade-off at 3.3 V. |
Compared with QPL9057 and SKY67151-396LF, OM7925/BGU7051,598 delivers the lowest noise figure in its 0.5–1.5 GHz band while maintaining the smallest footprint and lowest supply current - making it the preferred choice for thermally dense, power-constrained wireless infrastructure receivers.

FAQ
What is the recommended DC blocking capacitor value for OM7925/BGU7051,598 RF_IN and RF_OUT ports?
The datasheet specifies 1 nF for both C1 (RF_IN) and C2 (RF_OUT) DC blocking capacitors, using Murata GRM155 or equivalent 0402-size MLCCs. This value ensures full-bandpass operation from 500 MHz to 1500 MHz with insertion loss < 0.2 dB and maintains impedance integrity across the operating band.
Does OM7925/BGU7051,598 require external matching components for 50 Ω operation?
No - OM7925/BGU7051,598 is internally matched to 50 Ω at both RF_IN and RF_OUT terminals across 0.5–1.5 GHz. External matching networks are unnecessary, simplifying layout and improving repeatability in high-volume manufacturing.
What is the maximum allowable continuous RF input power for OM7925/BGU7051,598?
The absolute maximum continuous-wave RF input power is +20 dBm at VCC = 3.3 V, as defined in Table 4 (Limiting Values). Operation above this level risks permanent degradation of noise figure and gain linearity, even if within thermal limits.
How many ground connections does OM7925/BGU7051,598 have, and why are they important?
OM7925/BGU7051,598 has four dedicated GND terminals (pins 3, 5, 6, 8) to minimize ground loop inductance and ensure stable RF performance. Each must be connected via short, direct traces to a solid ground plane - critical for achieving specified NF, IP3, and unconditional stability.
Is OM7925/BGU7051,598 qualified for automotive applications?
No - OM7925/BGU7051,598 is not automotive-qualified. Per NXP's legal disclaimers, it is intended for wireless infrastructure use only and has not undergone AEC-Q100 stress testing or temperature cycling validation required for automotive deployment.
