Product details
Overview
SA607DK/01,118 from NXP Semiconductors (formerly Philips) is a low-voltage, monolithic FM intermediate frequency (IF) system IC integrating mixer/oscillator, dual limiting IF amplifiers, quadrature detector, temperature-compensated RSSI, voltage regulator, and audio/RSSI op amps. It operates down to 2.7V, delivers 17dB mixer conversion gain at 45MHz, achieves 102dB total IF/limiter gain, and supports RF input up to 150MHz - enabling portable cellular radio and cordless phone receivers.
For engineers reviewing the SA607DK/01,118 datasheet, SA607DK/01,118 pinout, SA607DK/01,118 application, or SA607DK/01,118 equivalent, key selection criteria include its 90dB RSSI dynamic range, 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/01,118 implements a single-conversion VHF receiver architecture with a Gilbert-cell mixer core, Hartley/Colpitts/Butler oscillator configurations supporting up to 150MHz crystal or LC operation, and cascaded IF amplification delivering 44dB IF amp gain + 58dB limiter gain. Its quadrature detector uses internal IF routing and external 90° phase-shift network for FM demodulation.
RSSI generation employs temperature-compensated logarithmic compression across –118dBm to –23dBm IF input levels (0.3–2.5V output), while dual buffered outputs - LIM OUT (Pin 11) and FREQ CHECK/LIM OUT (–) (Pin 9) - provide 115mVRMS into ≥2kΩ loads, 180° out of phase, enabling FSK demodulation or comparator-based AFC loops.

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/01,118 | Lower integration: lacks quadrature detector, RSSI, audio op amp, and second limiter; only mixer/oscillator + single IF amp | Suitable for simpler superhet receivers requiring external demodulation and signal-strength circuitry | Select when cost or die size constraints outweigh need for full IF integration |
| MAX2682EUT+T | Active mixer-only IC (no IF amps, detector, or RSSI); 400MHz–2.5GHz RF range; higher NF (8.5dB) but superior IP3 (–13dBm) | Targeted at UHF/SHF receivers where wide RF bandwidth and linearity supersede IF integration | Select for modern UHF IoT receivers needing high IP3 and wide tuning range, not legacy FM IF functions |
Compared with SA605D/01,118, the SA607DK/01,118 adds complete IF signal chain functionality - eliminating six external ICs - while MAX2682EUT+T trades integration for RF frequency agility and linearity, making it unsuitable as a drop-in replacement but viable for new UHF designs.

FAQ
What is the operating supply voltage range for the SA607DK/01,118?
The SA607DK/01,118 operates from 2.7V to 7.0V DC. Its 3.5mA typical quiescent current at 3V enables direct use with single-cell lithium or triple-AA battery supplies. The device maintains full specification compliance across this range, including 17dB mixer gain and 90dB RSSI dynamic range - critical for portable FM receiver designs where supply headroom is constrained.
Does the SA607DK/01,118 support crystal oscillator configurations above 100MHz?
Yes - the SA607DK/01,118 supports crystal oscillator frequencies up to 150MHz using a Butler oscillator configuration, as documented in the circuit description. Hartley or Colpitts topologies are recommended for up to 100MHz; Butler topology is explicitly specified for xtal operation beyond that. This capability allows direct 45MHz IF translation or VHF band coverage without external LO synthesis.
How does the SA607DK/01,118 interface with 455kHz ceramic filters?
The SA607DK/01,118 features 1.3–1.5kΩ IF input and output impedances (Pins 17 and 16) matched to standard Murata SFG455A3 and similar 455kHz ceramic filters. This eliminates the need for external impedance-matching networks - reducing component count and layout sensitivity. The datasheet confirms "no impedance matching network is necessary" for most 455kHz filters, simplifying design of compact FM receivers.
What is the functional difference between Pin 9 and Pin 11 on the SA607DK/01,118?
Pin 9 (FREQ CHECK / LIM OUT (–)) and Pin 11 (LIM OUT (+)) deliver identical 115mVRMS amplitude signals but with 180° phase difference. Both are buffered outputs of the final limiter stage. This differential pair enables zero-crossing detection for FSK demodulation or comparator-based AFC without external phase inversion - a key differentiator versus earlier SA605 variants which lack the buffered inverted output.
Is the SA607DK/01,118 pin-compatible with the SA607D variant?
Yes - SA607DK/01,118 (SSOP-20, SOT266-1) and SA607D (SOL-20, SOT163-1) share identical pin numbering, pin functions, and electrical specifications. The only difference is package geometry: DK uses narrower 4.4mm-body SSOP for higher-density layouts, while D uses 7.5mm-body SOL. PCB footprints are not interchangeable, but schematic design and firmware integration are fully compatible.
