Filter 150-175MHz


These single or cascadable high “Q” notch filters are very useful where either a local high level transmitter carrier or interfering signal requires attenuation (notching) between the antenna and receiver or where a transmitter needs isolation from a co-habited in-band transmitter which may be causing IM Products in the transmitter PA. Typical applications are where more than one mobile transceiver is operated on a vehicle and the in-band transmitter carriers have insufficient coupling isolation between antennas. Caution is however needed to ensure that the notched frequency is the >5MHz away from the wanted Tx and or Rx frequencies where a single cavity is used for notching. This frequency distance between the wanted and unwanted signal is marginally less where more than one notch filter is cascaded. The notch filter can be inserted anywhere along the feeder cable between the antenna and transceiver.
