SA606

Low-voltage high performance mixer FM IF system

1997 Nov 07

853-1576 18665

DESCRIPTION

The SA606 is a low-voltage high performance monolithic FM IF

system incorporating a mixer/oscillator, two limiting intermediate

frequency amplifiers, quadrature detector, logarithmic received

signal strength indicator (RSSI), voltage regulator and audio and

RSSI op amps. The SA606 is available in 20-lead SOL

(surface-mounted small outline large package) and 20-lead SSOP

(shrink small outline package).

The SA606 was designed for portable communication applications

and will function down to 2.7V. The RF section is similar to the

famous SA605. The audio and RSSI outputs have amplifiers with

access to the feedback path. This enables the designer to level

adjust the outputs or add filtering.

FEATURES

• Low power consumption: 3.5mA typical at 3V

• Mixer input to >150MHz

• Mixer conversion power gain of 17dB at 45MHz

• XTAL oscillator effective to 150MHz (L.C. oscillator or external

oscillator can be used at higher frequencies)

• 102dB of IF Amp/Limiter gain

• 2MHz limiter small signal bandwidth

• Temperature compensated logarithmic Received Signal Strength

Indicator (RSSI) with a 90dB dynamic range

• Low external component count; suitable for crystal/ceramic/LC

filters

• Excellent sensitivity: 0.31µV into 50Ω matching network for 12dB

SINAD (Signal to Noise and Distortion ratio) for 1kHz tone with RF

at 45MHz and IF at 455kHz

• SA606 meets cellular radio specifications

• Audio output internal op amp

• RSSI output internal op amp

• Internal op amps with rail-to-rail outputs
