Receive filters are sometimes
necessary to enhance the performance of broadband radios. The basic FM Notch filter, FLT201A
is a very useful complement to any monitoring site were VHF and UHF signals are monitored
on a regular basis. It is specially important in metropolitan and suburban areas were FM
signals are very strong compared to many other radio signals.
Possible problems with
strong signals, such as those from FM radio transmitters are:
1. RF overload
(reduces receiver sensitivity, increases noise)
2. Image mixing (two strong signals
mix and produce a third undesired signal).
The FLT225 is a High-Pass filter
designed primarily for radio monitoring of the military band (225
MHz to 400 MHz). This filter effectively attenuates signals below about
225 MHz, such as Paging (152/158 MHz), FM Radio and other strong business band radios.
The FLT225 uses the same die cast aluminum enclosure as the FM filter above, with
male/female BNC connectors.
is designed primarily as a BCB (AM radio) reject
filter in the form of a 7-section High-Pass-Filter. It can be used in any
receiver monitoring platform including as a complement to the Stridsberg
Engineering HF multicouplers, MCA102M, MCA104M and MCA108M. We have also
available special use filters such as FLT03
3 MHz High-Pass Filter and FLT10 10 MHz
Note: Coaxial interconnect cables are
available. RG-58A/U with BNC male connectors, sweep tested to 1.5 GHz.
