Product details
Overview
SA606DK,118 from NXP Semiconductors is a low-voltage monolithic FM IF system integrating mixer/oscillator, dual limiting IF amplifiers, quadrature detector, logarithmic RSSI, voltage regulator, and rail-to-rail audio/RSSI op amps. It operates down to 2.7 V, delivers 17 dB mixer conversion gain at 45 MHz, provides 102 dB total IF/limiter gain, and supports RF input up to 150 MHz - used in portable cellular radio FM IF receivers.
For engineers reviewing the SA606DK,118 datasheet, SA606DK,118 pinout, SA606DK,118 application, or SA606DK,118 equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases in wireless systems and RF level meters, and validated alternative options for FM IF signal chain design.
Technical Context
The SA606DK,118 implements a Gilbert-cell mixer with integrated oscillator capable of >150 MHz operation using crystal, LC, or external LO sources. Its IF path features two cascaded stages: a 43 dB-gain IF amplifier (5.5 MHz bandwidth) followed by a 60 dB-gain limiter (4.5 MHz bandwidth), optimized for 455 kHz ceramic filters with 1.5 kΩ impedance matching.
Quadrature detection uses internal IF-driven multiplication with externally AC-coupled 90° phase-shifted IF signal. Both audio and RSSI outputs employ rail-to-rail op amps with accessible feedback terminals for gain adjustment and filtering - enabling second-order temperature compensation of the 90 dB dynamic range RSSI output.

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,112 | Lower integration: no RSSI, no audio op amp, no quadrature detector - requires external limiter/demodulator | Suitable only for simple mixer+IF amp functions; cannot replace SA606DK,118 in RSSI/audio-critical designs | Select when cost and BOM count outweigh need for integrated demodulation and signal strength monitoring |
| MC3362P | Higher supply current (6.5 mA), wider supply range (4–8 V), no rail-to-rail outputs, older bipolar process | Legacy automotive/industrial FM receivers; lacks low-voltage portability and modern op amp flexibility | Choose only for drop-in replacement in existing MC3362-based designs where 2.7 V operation is not required |
Compared with SA606DK,118, SA605D,112 reduces system integration but sacrifices RSSI and audio functionality, while MC3362P offers legacy compatibility at the expense of power efficiency and design flexibility in portable applications.

FAQ
What is the minimum operating voltage for SA606DK,118?
The SA606DK,118 operates down to 2.7 V, enabling direct use with single-cell lithium-ion or alkaline batteries without intermediate regulation. This specification is guaranteed across the full −40 °C to +85 °C ambient temperature range and is validated in Table 6 of the NXP datasheet. The SA606DK,118 maintains full functionality including 17 dB mixer gain and 90 dB RSSI range at this voltage.
Does SA606DK,118 support external local oscillator injection?
Yes, SA606DK,118 supports external LO injection via the OSC_IN (pin 4) and OSC_OUT (pin 3) terminals. When using external LO, the internal oscillator is disabled, and the device achieves >150 MHz RF input capability. The datasheet confirms this mode in Section 7 and specifies 2.5 dB mixer conversion gain under 50 Ω source conditions with external LO.
How is the RSSI output calibrated on SA606DK,118?
The SA606DK,118 RSSI output is factory-calibrated for 90 dB dynamic range with ±1.5 dB variation over temperature. At RF = −68 dBm, SA606DK/01 and SA606DK/02 deliver 0.7–1.05 V output; SA606DK/03 delivers 1.06–1.15 V. These variants allow precise system-level RSSI scaling - confirmed in Table 7's Vo(RSSI) rows and Figures 13–14.
Can SA606DK,118 drive a 5 kΩ audio load directly?
Yes, SA606DK,118's audio op amp delivers rail-to-rail output and is specified to drive AC loads as low as 5 kΩ without distortion - stated explicitly in Section 7. This capability eliminates external buffer stages in portable radios and enables direct connection to analog-to-digital converters or audio codecs. The SA606DK,118 achieves 120 mV RMS audio output at −27 dBm RF input under these conditions.
What package type does SA606DK,118 use and what are its key mechanical features?
SA606DK,118 uses the SSOP20 package (SOT266-1) with 20 leads and 4.4 mm body width. Its lead pitch is 0.65 mm, and it complies with JEDEC MO-153 standards. The package supports reflow soldering only - wave soldering is not recommended due to fine pitch. Thermal resistance is 117 K/W (junction-to-ambient), per Table 5.
