SA637
Low-voltage digital IF receiver

October 27, 1993
853-1718 11205
DESCRIPTION
The SA637 is a low-voltage high performance
monolithic digital system with high-speed
RSSI incorporating a mixer, oscillator with
buffered output, two limiting intermediate
frequency amplifiers, fast logarithmic
received signal strength indicator (RSSI),
voltage regulator, RSSI op amp and power
down pin. The SA637 is available in SSOP
(shrink small outline package).
The SA637 was designed for portable digital
communication applications and will function
down to 2.7V. The limiter amplifier has
differential outputs with 2MHz small signal
bandwidth. The RSSI output has access to
the feedback pin. This enables the designer
to level adjust the outputs or add filtering.
