Mitigating Self-Generated Communications Interference

Inadequate isolation between a transmitter and a receiver in a cosite environment results in the receiver’s diminished ability to process a weak desired signal- a condition termed “desensitization”.

Mega-Pole™ Series 

           


The MEGA-POLE filter series covers the standard frequency bands within the 30 to 512 MHz range. This new filter series provides excellent selectivity while maintaining very low insertion loss. The product line also has exceptional RF power handling capability with a high third order intercept point. The MEGA-POLE filter series can be used for transmitter applications to reduce power amplifier noise, harmonics and intermodulation products, to provide bi-directional filtering directly at a transceiver’s antenna port, or other applications requiring extremely linear, high power RF bandpass filtering. It has been designed for rugged military environments per MIL-STD-810.
