SA636 - Low voltage high performance mixer FM IF system

Description

The SA636 is a low-voltage 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

Features

  • Wideband data output (600 kHz minimum).
  • Fast RSSI rise and fall times.
  • Low power consumption: 6.5 mA typical at 3 V.
  • Mixer input to >500 MHz.
  • Mixer conversion power gain of 11 dB at 240 MHz.
  • Mixer noise figure of 12 dB at 240 MHz.
  • XTAL 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.
  • Temperature compensated logarithmic Received Signal S.

SA636 Low voltage high performance mixer FM IF system with high-speed RSSI Rev. 8 — 8 October 2019 Product data sheet 1. General description The SA636 is a low-voltage 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 SA636 is available in 20-lead SSOP (Shrink Small Outline Package) and HVQFN20 (quad flat package). The SA636 was designed for high bandwidth portable communication applications and will function down to 2.7 V. The RF section is similar to the famous SA605. The data output has a minimum bandwidth of 600 kHz.
