This premium High Pass BCB Rejection Filter filter is designed with a corner frequency (-3 dB point) of 1.83 MHz. It was specically designed to reject the numerous 10 kw AM transmitters that have been allocated to the extended AM (1.6 to 1.7 MHz) broadcast band within the USA while still providing excellent 160m ham band performance. It is designed to be used as a receive only filter. Distinguished characteristics are as follows:
The design is completely passive to eliminate any possibility of noise or distortion.
The design uses high Q torroidal inductors to provide an extremely sharp filter response.
High Ultimate Rejection
Static protection is provided on the input.
The filter is housed in an rf tight/shielded cast aluminum enclosure.
