Band Pass Band Reject 4 meter Filter BPBR4/4

25.00

BPBR 4/4 / BRBP 4/4 Pic is the 2 cavity device NEW OLD STOCK
Band-Pass – Band-Reject Filters for the 80 MHz Band
DESCRIPTION
The BPBR 4/4? and the BRBP 4/4? are 4-cavity pass-reject filters,
which pass one frequency or frequency band and reject another in
immediate vicinity of the pass frequency.
The filters are delivered in two basic models: The BPBR-types have the
reject range on the high side of the pass frequency and the BRBP-types
have the reject range situated on the low side of the pass frequency.
These filter types can be used to protect a receiver against interference
from a nearby transmitter. The filters are tuned to reject the interfering
signal. Pass-reject-type filters are applied when the spacing between the
utility signal and the interfering signal is so small, that the slope
steepness of normal band-pass filters or notch filters are not sufficient to
provide adequate rejection.
The filters are primarily intended to pass and reject two single
frequencies, but the filters can also be tuned to pass and reject several
single frequencies or to having a certain pass and reject port bandwidth.
In these cases factory-tuning is recommended
