MEGA-POLE filter series

MEGA-POLE®

The MEGA-POLE® filter series covers the standard frequency bands within the 30 to 450 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.

Pole/Zero’s MEGA-POLE® Filter offers high selectivity with 251 tunable positions per band, utilizing a 2-pole, constant Q design. With a flat response in the passband and roll offs toward zero in the stopband, the MEGA-POLE® Filter is recognized for exceptional RF power handling capabilities with a high third order intercept point.

The series is ideal for transmitter applications but offers flexible enhancements for versatile performance across multiple use cases.
