NXP Semiconductors OM7623/BFU725F/2400,598

Overview

OM7623/BFU725F/2400,598 from NXP Semiconductors is a fully assembled 2.4 GHz low-noise amplifier evaluation board built around the BFU725F/N1 SiGe HBT transistor in SOT343F package. It delivers 15.3 dB power gain, 1.0 dB noise figure, and >6 dB input return loss at 2.4 GHz for ISM-band LNA validation in wireless LAN and Bluetooth systems.

For engineers reviewing the OM7623/BFU725F/2400,598 datasheet, OM7623/BFU725F/2400,598 pinout, OM7623/BFU725F/2400,598 application, or OM7623/BFU725F/2400,598 equivalent, this board enables rapid RF performance verification-requiring only 3 V DC supply and SMA-connected test equipment-with no external matching or bias circuitry needed.

Technical Context

The OM7623/BFU725F/2400,598 implements a fixed-gain, single-stage LNA topology using the BFU725F/N1 transistor biased at 3 V and ~8 mA. Input and output are matched via discrete 0402 inductors (L1 = 12 nH, L3 = 5.6 nH) and capacitors to achieve broadband 2.4 GHz operation with K > 1 stability margin.

It uses FR4 PCB material (ε_r = 4.6–4.9, tan δ = 0.02) with controlled-impedance microstrip traces, dual-emitter grounding vias, and on-board 3-way right-angle DC header (Molex 90121-0763) for bias control. SMA connectors (Johnson 142-0701-841) provide calibrated RF I/O interfaces.

FAQ

What is the primary function of the OM7623/BFU725F/2400,598 evaluation board?

The OM7623/BFU725F/2400,598 evaluation board is a ready-to-use 2.4 GHz low-noise amplifier test platform centered on the BFU725F/N1 SiGe HBT transistor. It provides calibrated RF input/output via SMA connectors, fixed biasing, and optimized matching to enable immediate measurement of gain, noise figure, and linearity without additional circuit design. The OM7623/BFU725F/2400,598 eliminates the need for custom layout or impedance tuning during early-stage RF validation.

Does the OM7623/BFU725F/2400,598 require external power regulation or decoupling?

No-the OM7623/BFU725F/2400,598 operates directly from a stable 3 V DC source and integrates all necessary decoupling: four 0402 ceramic capacitors (C3, C4, C5, C6) handle low-frequency bypassing, while the PCB layout routes bias lines with minimal inductance. The OM7623/BFU725F/2400,598 draws ~8 mA and requires no external regulators, ferrites, or bulk capacitance for functional testing.

Can the OM7623/BFU725F/2400,598 be used outside the 2.4 GHz ISM band?

Yes-the BFU725F/N1 transistor supports operation up to 15 GHz, and the OM7623/BFU725F/2400,598 board's matching network can be modified for other frequencies. However, its default component values (e.g., L1 = 12 nH, L3 = 5.6 nH) and layout are optimized for 2.4 GHz; performance metrics like NF and gain degrade outside that band without re-tuning. The OM7623/BFU725F/2400,598 serves as a reference starting point-not a multi-band solution.

What test equipment is required to evaluate the OM7623/BFU725F/2400,598?

A 3 V DC power supply, 2.4 GHz RF signal generator, and spectrum analyzer (or vector network analyzer) are essential. A noise figure analyzer-or spectrum analyzer with noise option plus 5 dB noise source-is required for NF measurement. The OM7623/BFU725F/2400,598 connects directly via SMA ports; no adapters or cables beyond standard 50 Ω test fixtures should be used to preserve measurement accuracy.

Is the OM7623/BFU725F/2400,598 RoHS-compliant and lead-free?

Yes-the OM7623/BFU725F/2400,598 evaluation board complies with RoHS Directive 2011/65/EU and uses lead-free solder and components. All passive parts (Murata GRM1555 capacitors, Murata inductors) and connectors (Johnson SMA, Molex header) listed in the BOM meet NXP's environmental specifications. The OM7623/BFU725F/2400,598 documentation confirms full compliance per NXP's product change notifications.
