SA615
High performance low power mixer FM IF system
Rev. 4 — 14 November 2014
Product data sheet
1. General description
The SA615 is a high performance monolithic low-power FM IF system incorporating a
mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector,
muting, logarithmic Received Signal Strength Indicator (RSSI), and voltage regulator. The
SA615 combines the functions of NXP Semiconductors SA602A and SA604A, but
features a higher mixer input intercept point, higher IF bandwidth (25 MHz) and
temperature compensated RSSI and limiters permitting higher performance application.
The SA615 is available in 20-lead SO (surface-mounted miniature package) and 20-lead
SSOP (shrink small outline package).
The SA605 and SA615 are functionally the same device types. The difference between
the two devices lies in the guaranteed specifications. The SA615 has a higher ICC, lower
input third-order intercept point, lower conversion mixer gain, lower limiter gain, lower AM
rejection, lower SINAD, higher THD, and higher RSSI error than the SA615. Both the
SA605 and SA615 devices meet the EIA specifications for AMPS and TACS cellular radio
applications.
2. Features and benefits
Low power consumption: 5.7 mA typical at 6 V
Mixer input to >500 MHz
Mixer conversion power gain of 13 dB at 45 MHz
Mixer noise figure of 4.6 dB at 45 MHz
XTAL oscillator effective to 150 MHz (L/C oscillator to 1 GHz local oscillator can be
injected)
102 dB of IF amplifier/limiter gain
25 MHz limiter small signal bandwidth
Temperature-compensated logarithmic Received Signal Strength Indicator (RSSI) with
a dynamic range in excess of 90 dB
Two audio outputs — muted and unmuted
Low external component count; suitable for crystal/ceramic/LC filters
Excellent sensitivity: 0.22 V into 50 matching network for 12 dB SINAD
(Signal-to-Noise-and-Distortion ratio) for 1 kHz tone with RF at 45 MHz and IF at
455 kHz
SA615 meets cellular radio specifications
ESD hardened
