FEATURES

DESCRIPTION

•

ULTRA LOW INTERMODULATION DISTORTION

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 (IP₂and IP₃) of 90 dBm and 45 dBm respectively.
