Pre-Filtered RF Preamplifier

 

From 300kHz to 500MHz range of eleven Pre-Filtered, Very Low Noise, High IP3 preamplifiers.

Suitable as IF Buffer for SDR radios, instrumentation and general purpose applications.

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

 

 
 

Range of high performance Pre-Filtered 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.

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

Available Low Pass Filter frequencies to choose:

- 300kHz
- 600kHz
- 1.5MHz
- 3MHz
- 6MHz
- 15MHz
- 30MHz
- 60MHz
- 150MHz
- 300MHz
- 500MHz

Depending on the working frequency technical features are as follows:
