Range of Prefiltered RF Preamplifiers

 

From 100kHz to 500MHz range of thirty four prefiltered, Very Low Noise, High IP3 preamplifiers.

For general purpose use such as Antenna signal booster, Instrumentation and IF Buffer for SDR radios, applications.

Featuring Amplifier By-Pass function when the toggle switch is set to amplifier OFF position.

 

 
 

Range of high performance prefiltered RF Preamplifiers incorporating a 7th order Elliptic Low Pas Filter prior a high IP3, low noise amplifier.

High IP3 is an important feature denoting capability to handle strong signals without distortion.

Suitable for a wide range of purposes in applications such as IF buffer for SDRradios, signal booster for radio receivers, laboratory measurement, signal generation, local oscillator buffer, transmission driver, etc.
