Product details
Overview
SA607DK/01,112 from Philips Semiconductors is a low-voltage monolithic FM intermediate frequency (IF) system integrating mixer/oscillator, dual limiting IF amplifiers, quadrature detector, temperature-compensated logarithmic RSSI, voltage regulator, and buffered audio/RSSI op amps. It operates down to 2.7V, delivers 17dB mixer conversion gain at 45MHz, provides 90dB RSSI dynamic range, and supports up to 150MHz RF input - designed for portable cellular radio and narrowband FM receivers.
For engineers reviewing the SA607DK/01,112 datasheet, SA607DK/01,112 pinout, SA607DK/01,112 application, or SA607DK/01,112 equivalent, key selection criteria include its integrated IF signal chain architecture, rail-to-rail op amp outputs, buffered frequency-check output for AFC implementation, and compatibility with 455kHz ceramic filters without external impedance matching.
Technical Context
The SA607DK/01,112 implements a complete single-chip FM IF subsystem: a Gilbert-cell mixer with on-chip oscillator (XTAL/LC/external), two cascaded limiting IF amplifiers (44dB + 58dB gain), a quadrature detector with internal 90° phase shift network, and dual op amps for audio and RSSI conditioning. Its RF input stage features 8kΩ single-ended resistance and 3.5pF capacitance, while the mixer output presents 1.5kΩ impedance for direct ceramic filter interfacing.
It integrates a temperature-compensated logarithmic RSSI with ±1.5dB accuracy across –118dBm to –23dBm IF input levels, and provides two buffered limiter-derived outputs - Pin 11 (LIM OUT(+)) and Pin 9 (FREQ CHECK/LIM OUT(–)) - 180° out of phase, each capable of driving ≥2kΩ loads with 115mVRMS output.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar FM IF system applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SA605D/01,112 | Predecessor IC; lacks integrated quadrature detector, RSSI, and audio op amp - requires external components for full IF function | Suitable only for designs where RSSI and audio amplification are handled externally | Select SA605D/01,112 only when legacy design reuse or cost-sensitive applications justify added external circuitry |
| MAX2102ETJ+ | Modern 3.3 V CMOS IF receiver; includes digital RSSI, SPI interface, and programmable gain - not pin-compatible | Targets digitally controlled receivers requiring configuration flexibility and lower power than SA607DK/01,112 | Choose MAX2102ETJ+ for new designs needing digital control, but expect layout and firmware redesign |
Compared with SA605D/01,112, SA607DK/01,112 integrates full IF demodulation and monitoring functions in one package, reducing component count and layout complexity; versus MAX2102ETJ+, it offers analog simplicity and proven RF performance but lacks digital configurability and modern process advantages.

FAQ
What is the operating supply voltage range for the SA607DK/01,112?
The SA607DK/01,112 operates from 2.7 V to 7.0 V DC. At 3 V, it draws 3.5 mA typical quiescent current, making it ideal for single-cell lithium or triple-cell alkaline battery systems. Performance parameters including noise figure, conversion gain, and IIP3 are specified across this full range, with data showing stable operation up to 85°C ambient.
Does the SA607DK/01,112 support external oscillator configurations?
Yes, the SA607DK/01,112 supports multiple oscillator modes: crystal (up to 150 MHz using Butler topology), LC tank (beyond 150 MHz), or fully external LO injection via OSCIN (Pin 4). The datasheet confirms effective crystal oscillator operation to 150 MHz and notes Hartley/Colpitts configurations for frequencies up to 100 MHz - all validated for SA607DK/01,112.
How is the RSSI output of the SA607DK/01,112 calibrated and what is its accuracy?
The SA607DK/01,112 features a temperature-compensated logarithmic RSSI with ±1.5 dB accuracy over its 90 dB dynamic range (–118 dBm to –23 dBm IF input). Output voltage spans 0.3 V to 2.5 V, and calibration is factory-trimmed - confirmed by Figures 15 and 16 in the official Philips specification document for SA607DK/01,112.
Can the SA607DK/01,112 be used for FSK demodulation?
Yes, the SA607DK/01,112 supports FSK demodulation using its dual buffered limiter outputs: Pin 11 (LIM OUT(+)) and Pin 9 (FREQ CHECK/LIM OUT(–)) are identical in amplitude but 180° out of phase. This differential pair can feed a comparator to recover FSK data - explicitly stated in the "Circuit Description" section of the SA607DK/01,112 datasheet.
What package type does SA607DK/01,112 use and is it RoHS-compliant?
The SA607DK/01,112 uses a 20-lead plastic shrink small outline package (SSOP) per SOT266-1, with 4.4 mm body width. While the original 1997 datasheet predates RoHS, current Aetrix Electronics inventory carries lead-free, RoHS-compliant SA607DK/01,112 units manufactured under NXP's qualified requalification program - full compliance documentation available upon request.
