DESCRIPTION
The Comstron Model FA4489 is a switchable filter mod-
ule with the capability of selecting any one of nine chan-
nels with a four TTL control signal. This device is used
as the front-end preselector in a high dynamic range
receiver. The filter module introduces very low inter-
modulation distortion along with low insertion loss - a
necessary requirement for excellent receiver perfor-
mance.
ULTRA LOW INTERMODULATION
DISTORTION
Comstron has developed a proprietary switching matrix
that spans 1 MHz to 1200 MHz (more than 3 decades
wide) along with introducing low intermodulation dis-
tortion and low signal loss. The pin diodes utilized in
the SP9T switch are optimum for high- lifetime carrier,
low junction capacitance and low series resistance and
help produce second and third order output intercept
points (IP
2
and IP
3
) of 90 dBm and 45 dBm respectively.
