The SA615D/01.112 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 (25MHz) and temperature compensated RSSI and limiters permitting higher performance application. 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. The SA615 device meets the EIA specifications for AMPS and TACS cellular radio applications.

• 5.7mA typical at 6V Low power consumption
• Mixer input to >,500MHz
• Mixer conversion power gain of 13dB at 45MHz
• Mixer noise figure of 4.6dB at 45MHz
• XTAL oscillator effective to 150MHz (L/C oscillator to 1GHz local oscillator can be injected)
• 102dB of IF amplifier/limiter gain
• 25MHz limiter small signal bandwidth
• Two audio outputs - muted and unmated
• Low external component count, suitable for crystal/ceramic/LC filters
• SA615 meets cellular radio specifications
