Product details
Overview
SA606DK/01,118 from NXP Semiconductors is a low-voltage high-performance 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 in a 20-pin SSOP package. It operates down to 2.7 V, delivers 17 dB mixer conversion gain at 45 MHz, 102 dB total IF/limiter gain, and 90 dB RSSI dynamic range - enabling portable cellular radio FM IF receivers with 0.31 µV sensitivity into 50 Ω.
For engineers reviewing the SA606DK/01,118 datasheet, SA606DK/01,118 pinout, SA606DK/01,118 application, or SA606DK/01,118 equivalent, this page provides verified technical context, validated pin functions, real-world RF/IF performance metrics, and confirmed alternatives for FM receiver design, spectrum analysis, and wireless instrumentation systems.
Technical Context
The SA606DK/01,118 implements a complete second-IF signal chain: a Gilbert-cell mixer with on-chip oscillator (effective to 150 MHz), two cascaded limiting IF amplifiers (43 dB + 60 dB gain), a quadrature detector with internal IF reference, and dual rail-to-rail op amps for audio and RSSI outputs. Its 1.5 kΩ IF input/output impedance enables direct connection to 455 kHz ceramic filters without matching networks.
It supports crystal, LC, or external LO configurations; features temperature-compensated logarithmic RSSI with ±1.5 dB variation over −40 °C to +85 °C; and includes ESD protection exceeding 2000 V HBM and latch-up immunity per JEDEC JESD78 Class II, Level B - all optimized for battery-powered portable communication receivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 7.0 V - enables single-cell Li-ion or dual-cell alkaline operation without regulation overhead. |
| Supply Current | 3.5 mA typical at 3 V - ensures ultra-low power consumption for extended portable device battery life. |
| Mixer Conversion Gain | 17 dB at 45 MHz - provides sufficient signal level to drive downstream 455 kHz ceramic filters directly. |
| IF/limiter Small-Signal Bandwidth | 2 MHz - supports wideband FM demodulation and FSK/ASK data reception up to ~1 MHz symbol rate. |
| RSSI Dynamic Range | 90 dB - enables precise RF signal strength measurement across cellular, cordless, and instrumentation use cases. |
| Noise Figure | 6.2 dB at 45 MHz - ensures high sensitivity (0.31 µV for 12 dB SINAD) in weak-signal portable receiver applications. |
| Input Third-Order Intercept | −9 dBm - delivers robust linearity for multi-channel RF environments with adjacent channel interference. |
Pinout & Package
SA606DK/01,118 is housed in a plastic shrink small outline package (SSOP20) per SOT266-1, with 20 leads, 4.4 mm body width, and 0.65 mm lead pitch - optimized for high-density PCB layouts in portable radios and handheld test equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RF_IN | RF input terminal | Single-ended 8 kΩ input for 150 MHz RF signals; requires decoupling at Pin 2. |
| 3 OSC_OUT / 4 OSC_IN | Oscillator interface | Supports crystal (≤150 MHz), LC tank, or external LO; enables Hartley/Colpitts/Butler topologies. |
| 10 QUADRATURE_IN | Quadrature detector input | Receives phase-shifted IF signal for zero-crossing FM demodulation; AC-coupled to tuned network. |
| 7 AUDIO_FEEDBACK / 9 RSSI_FEEDBACK | Negative feedback terminals | Allow external gain setting, filtering, or second-order temperature compensation of op amp outputs. |
| 11 LIMITER_OUT / 16 IF_AMP_OUT | Amplifier outputs | Drive 455 kHz ceramic filters directly; 1.5 kΩ output impedance matches standard IF filter Z₀. |
| 15 GND | Ground reference | Common return for analog/RF sections; must be low-impedance plane for noise-sensitive IF performance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail op amps | Audio and RSSI outputs swing within 20 mV of supply rails - simplifies interfacing to ADCs or analog meters without level-shifting. |
| Temperature-compensated RSSI | ±1.5 dB RSSI variation over −40 °C to +85 °C - eliminates calibration drift in field-deployed RF level meters and spectrum analyzers. |
| Low external component count | Direct 455 kHz ceramic filter compatibility - reduces BOM cost and board area vs. discrete IF chains requiring matching networks. |
| High mixer linearity | −9 dBm IIP3 - maintains signal integrity in crowded RF bands such as cellular base stations or multi-channel cordless phones. |
| ESD and latch-up robustness | 2000 V HBM / 1000 V CDM ESD rating and JEDEC JESD78 Class II compliance - ensures reliability in hand-held assembly and end-use environments. |

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: no RSSI, no audio op amp, no quadrature detector; only mixer + oscillator + IF amp. | Suitable for simpler superhet receivers where RSSI and audio output are handled externally. | Select when system already includes discrete RSSI/log amp and audio buffer; saves cost where full SA606 functionality is unused. |
| MC3362DR2G | Higher supply current (6.5 mA), wider supply range (4.0–8.0 V), no rail-to-rail op amps, different pinout and IF architecture (dual-conversion capable). | Better suited for fixed-station receivers and legacy automotive radios requiring higher IF gain stability. | Choose for industrial-grade thermal performance above +85 °C or where existing MC3362-based designs require drop-in replacement with layout adaptation. |
Compared with SA606DK/01,118, SA605D/01,118 reduces integration to save cost in basic receivers, while MC3362DR2G trades lower power and compact SSOP packaging for higher supply headroom and legacy system compatibility - making SA606DK/01,118 optimal for new portable, battery-constrained FM IF designs.

FAQ
What is the minimum operating voltage for SA606DK/01,118?
The SA606DK/01,118 operates down to 2.7 V, enabling direct use with single-cell lithium-ion batteries or two-cell alkaline supplies without voltage regulation. This low-voltage capability is confirmed in Table 6 (Static Characteristics) of the NXP datasheet Rev. 6, where VCC min = 2.7 V at Tamb = 25 °C.
Does SA606DK/01,118 support crystal oscillator configurations?
Yes, SA606DK/01,118 supports crystal oscillator configurations up to 150 MHz using Butler oscillator topology, as stated in Section 2 (Features and benefits) and Section 7 (Functional description). Pins 3 (OSC_OUT) and 4 (OSC_IN) provide dedicated connections for crystal or LC tank implementation.
What is the RSSI output voltage range of SA606DK/01,118 at −68 dBm RF input?
At −68 dBm RF input level, the SA606DK/01,118 delivers an RSSI output voltage of 0.7 V to 1.8 V, as specified in Table 7 (Dynamic characteristics) under Vo(RSSI) conditions for SA606DK/01 variant. This 1.1 V span corresponds to its 90 dB dynamic range with ±1.5 dB variation.
Can SA606DK/01,118 drive a 455 kHz ceramic filter directly?
Yes, SA606DK/01,118 can drive a 455 kHz ceramic filter directly due to its 1.5 kΩ IF amplifier output impedance (Pin 16) and matching 1.5 kΩ limiter input impedance (Pin 14), eliminating the need for external impedance-matching networks - a key design advantage confirmed in Section 7 and Figure 16.
Is SA606DK/01,118 pin-compatible with SA606D/01,118?
No, SA606DK/01,118 is not pin-compatible with SA606D/01,118 despite identical functionality: SA606DK/01,118 uses SSOP20 (SOT266-1) with 0.65 mm pitch, while SA606D/01,118 uses SO20 (SOT163-1) with 1.27 mm pitch - requiring distinct PCB footprints and layout adaptations.
