Tx  filters

A family of high-selectivity filters installed in the RF transmission path between radio communication transmitters and antennas to suppress spurious harmonics and out-of-band noise, thereby allowing co-located operation of power transmitters with receivers.

Filter types:

• band-pass type filters tuned to the transmitter frequency, which provide high attenuation for  the transmitter out-of-band noise

• high-selectivity notch-type filters, tuned to selected frequencies to remove transmitter spurious
