What is it?

The HT004 is a professional-grade Low Noise Amplifier (LNA) module designed for broadband RF signal reception across a wide frequency range of 0.1MHz to 6GHz. Built with a rugged metal casing and equipped with the high-performance TQP3M9037-LNA, it delivers outstanding 20dB gain, ultra-low noise figure, and high linearity (+35dBm output IP3).

This RF amplifier module is ideal for enhancing weak signals in shortwave receivers, FM radios, remote control systems, and cable TV signal amplifiers, ensuring stable and clean signal boosting.

Why did us make it?

In RF DIY projects, having a reliable, unconditionally stable, and wideband LNA is essential to achieving optimal sensitivity and reception.

Many off-the-shelf solutions compromise either on noise figure, gain stability, or durability.

We designed the HT004 to meet the high expectations of RF enthusiasts, ham radio operators, and DIY engineers — providing a ready-to-use, compact, and efficient wideband RF preamplifier.

What makes it special?

Wide Frequency Range (0.1MHz–6GHz): Supports a vast spectrum of RF applications, from shortwave to microwave bands.

High Gain 20dB: Perfect for boosting weak signals without significant distortion.

Ultra Low Noise: Built for maximum signal clarity with minimal noise figure degradation.

High Linearity: +35dBm output IP3 and rugged input handling up to +22dBm CW.

Stable & Durable: Excellent uniformity, corrosion-resistant metal housing, and unconditional RF stability.

DIY Friendly: SMA female connectors for easy integration into your custom builds.

Flexible Power Input: Operates at 5V/70mA. Optionally supports 3.7V 300mAh lithium battery (not included).
