Designers of S-Band communications systems are often times
confronted with recive side link scenarios where near channel
frequencies will, on occasion, provide significant interference
to the channel of interest. Unfortunately, this frequently
renders the receive data as totally unusable during periods
of active near channel operation.
In order to combat these anomalies, SRI has developed the
SP-1220 Preselector System as an adjunct to its standard
SR-1120A S-Band Receive System. The latest technology product
provides RF channel selection within the 2202.5 MHz to 2297.5
MHz frequency spectrum. All channel selection and monitoring
of the SP-1220 operation is performed automatically by the
SR-1120A.
Designed for maximum interfering signal rejection while
maintaining minimum signal-of--interest insertion loss,
this product is ideally suited for system integrators confronted
with these types of challenges.
By utilizing 20 miniaturized, individually tuned, mechanical
combline filters, the SP-1220 satisfies these high performance
requirements while still maintaining a minimum form/fit
packaging fully compatible with typical ground mobile, transport
case, or ground station deployments. The Preselector is
contained within an industry standard 1U 19 inch rack mount
chassis and receives all status, control and power interfaces
directly from existing SRI S-Band Receive Systems.
Custom features, including alternate frequency bands and/or
different status/control interfaces, can be readily accomodated
into the highly modularized design. Consult the factory
for custom options.
