Beschreibung :
The SA58641 is a high performance monolithic FM IF system with high-speed RSSI
incorporating a mixer/oscillator,two limiting intermediate frequency amplifiers, quadrature
detector, logarithmic Received Signal Strength Indicator (RSSI), voltage regulator,
wideband data output and fast RSSI op amps. The SA58641 is available in 20-lead SSOP
(Shrink Small Outline Package).
♦ Wideband data output (600 kHz minimum)
♦ Fast RSSI rise and fall times
♦ Low power consumption: 7.5 mA typical at 5 V
♦ Mixer input to >500 MHz
♦ Mixer noise figure of 12 dB at 240 MHz
♦ Crystal oscillator effective to 150 MHz (LC oscillator to 1 GHz local oscillator can be
injected)
♦ 92 dB of IF amp/limiter gain
♦ 25 MHz limiter small signal bandwidth
