JinTaoRui SBB5089 RF Amplifier Module

The JinTaoRui SBB5089 is a wideband RF amplifier module built on an InGaP HBT MMIC Darlington configuration with an active bias network. It operates from a single 5V supply without a dropping resistor and covers a frequency range of 50MHz to 6000MHz. The module provides a typical gain of 20dB and is internally matched to 50 ohms. It suits engineers and hobbyists needing a compact pre-amplifier for weak signal chains or PA driver stages.

Sustained thermal behaviour and linearity

The active bias network maintains stable current over temperature and process Beta variations, while the fine thermal design keeps thermal resistance low. At 1950MHz the module delivers a P1dB of 20.4dBm and an output IP3 of 38dBm, with a noise figure of 4.2dB at 1000MHz. Maximum input power is rated at +23dB. Wideband flat gain holds to 1.1dB up to 4GHz, supporting consistent performance during continuous operation.

Upgrade path and fit

This module replaces discrete Darlington gain blocks that require external bias resistors and additional matching components. The jump is worth it when a design needs a single 5V supply, integrated 50 ohm matching, robust 1000V ESD Class 1C protection, and a footprint of 49 by 25mm. It is not for builders who need a complete wireless adapter with antenna, enclosure or host interface, nor for systems requiring integrated filtering or digital control.

Questions about this item

How much heat does the 5 V supply generate when the SBB5089 runs at 20 dB gain all day?

The module draws power from a single 5 V rail with an active bias network that keeps current stable over temperature, and its fine thermal design with low thermal resistance helps dissipate heat during continuous operation.

What external components are needed to power and connect the SBB5089 module?

A 5 V supply, 50-ohm source and load, and SMA or equivalent RF connectors for the input and output ports are required; no dropping resistor is needed because the active bias network handles biasing internally.

Will the 50 MHz–6000 MHz range and 50-ohm impedance match my existing RF chain?

The amplifier covers 50 MHz to 6000 MHz with a flat gain of 1.1 dB to 4 GHz and is internally matched to 50 ohms, so it interfaces directly with standard 50-ohm cables, antennas and test equipment.
