Waveguide Reject Filters

Drawcom transmit and receive reject filters are designed for use in satellite earth station equipment. The Tx reject filters are designed to be used on receive systems to reject any spurious signals in the transmit frequency, while the Rx reject filters are used on transmit systems to reject any spurious signals in the receive frequency.
