Product details
Overview
OM7808/BGU7003W/FM from NXP Semiconductors is a high-ohmic FM low-noise amplifier MMIC designed for impedance matching between embedded antennas and FM radio receivers in portable devices. It delivers 13 dB gain, 1.2 dB noise figure, and -23 dBm input P1dB at 100 MHz with 2.85 V supply and 3.2 mA total current. Used in mobile phone FM radio front-ends to enable speaker playback of weak broadcast signals.
For engineers reviewing the OM7808/BGU7003W/FM datasheet, OM7808/BGU7003W/FM pinout, OM7808/BGU7003W/FM application, or OM7808/BGU7003W/FM equivalent, key selection criteria include FM band (76–108 MHz) noise performance, high-input-impedance architecture for embedded antenna interface, DC bias stability, and minimal external component count (8–9 passive parts).
Technical Context
The OM7808/BGU7003W/FM implements a monolithic microwave integrated circuit topology optimized for high-impedance FM antenna coupling, eliminating need for impedance-transforming baluns. Its internal bias network sets stable 2.85 V operation with 3.2 mA total current across RF_IN, RF_OUT, and R_BIAS paths.
Measured on an evaluation board with SMA reference planes, it achieves 0.5 dB input return loss and 16.5 dB output return loss at 100 MHz under 50 Ω source/load conditions. Third-order intercept points are IP3I = -15 dBm and IP3O = -2 dBm with -30 dBm dual-tone input.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FM LNA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QPL9057 | Higher gain (15.5 dB), wider bandwidth (50–1200 MHz), but higher NF (1.5 dB) and 5 V supply requirement. | Designed for multi-band receivers; less optimized for FM-only, low-voltage portable use. | Prefer when multi-band support or higher gain margin is needed; requires level-shifting for 2.85 V systems. |
| Skyworks SKY65168-360LF | FM-optimized (76–108 MHz), 1.3 dB NF, 12.5 dB gain, 2.7–5.5 V supply range, SOT-363 package. | Larger footprint (2.1 × 2.0 mm) and higher current (4.5 mA); includes integrated ESD protection. | Select when board space allows larger package and integrated ESD is preferred over discrete PESD5V0F1BL. |
Compared with QPL9057 and SKY65168-360LF, OM7808/BGU7003W/FM offers the lowest noise figure (1.2 dB) and smallest footprint (1.0 × 0.6 mm) at 2.85 V, making it optimal for space- and power-constrained FM-only mobile designs where antenna impedance mismatch is dominant.

FAQ
What is the primary function of the OM7808/BGU7003W/FM in an FM radio system?
The OM7808/BGU7003W/FM serves as a high-impedance low-noise amplifier that bridges embedded antennas to standard 50 Ω FM receiver inputs. It solves impedance mismatch issues by accepting high-Z antenna signals directly-without baluns-and provides 13 dB gain with 1.2 dB noise figure. This function is critical in mobile phones where antenna size limits efficiency and signal strength.
Does the OM7808/BGU7003W/FM require external bias components?
No, the OM7808/BGU7003W/FM integrates its bias network internally. Application note AN11034 confirms that only a single 2.85 V supply on pin 4 (VCC) is needed-no external gate/base resistors or bias tees are required. This simplifies layout and improves thermal stability across operating temperatures compared to discrete bias solutions.
What is the recommended PCB layout practice for the OM7808/BGU7003W/FM?
Per AN11034, the OM7808/BGU7003W/FM requires a solid RF ground plane with low-inductance vias beneath pin 2 (GND), short microstrip traces to RF_IN and RF_OUT, and decoupling capacitors (47 nF) near VCC. The reference design uses SMA connectors for measurement; layout footprints reserve space for optional 0402 ESD protection diodes like PESD5V0F1BL.
Can the OM7808/BGU7003W/FM operate outside the FM broadcast band?
No-the OM7808/BGU7003W/FM is optimized exclusively for 76–108 MHz. Measurement data in AN11034 shows peak gain, noise figure, and return loss performance within this band; performance degrades significantly below 70 MHz or above 115 MHz. It is not intended for VHF TV, AM, or ISM band use.
How does the OM7808/BGU7003W/FM handle ESD protection?
The OM7808/BGU7003W/FM does not integrate ESD protection. AN11034 explicitly lists D2 (PESD5V0F1BL) as an optional external ESD diode placed at the RF_IN node. Designers must include this or equivalent 5 V-rated bidirectional TVS diode to meet IEC 61000-4-2 Level 4 requirements in end-product certifications.
