Product details
Overview
SA602AN/01,112 from NXP Semiconductors is a low-power VHF monolithic double-balanced mixer with integrated input amplifier, on-board oscillator, and voltage regulator. It delivers 17 dB typical conversion gain at 45 MHz, <5.0 dB noise figure, and −13 dBm input third-order intercept point, operating from 4.5 V to 8.0 V supply with 2.4 mA typical current draw. Designed for cellular radio front-ends, it enables compact, battery-efficient RF downconversion in portable transceivers.
For engineers reviewing the SA602AN/01,112 datasheet, SA602AN/01,112 pinout, SA602AN/01,112 application, or SA602AN/01,112 equivalent, key selection considerations include its Gilbert-cell architecture, 200 MHz max oscillator frequency, SO8 package compatibility, and verified performance in 45 MHz IF cellular receiver stages.
Technical Context
The SA602AN/01,112 implements a differential Gilbert-cell multiplier core with internally biased RF inputs (1.5 kΩ || 3 pF) and balanced mixer outputs (1.5 kΩ pull-up per output). Its oscillator supports crystal, tuned-tank, or external LO configurations up to 200 MHz, with OSC_B (pin 6) accepting ≥200 mVPP external drive via DC blocking capacitor.
Functional integration includes a temperature-compensated bias network and on-chip voltage regulation, enabling stable operation across −40 °C to +85 °C ambient. The device's 14–17 dB conversion gain and −13 dBm IP3i are specified at 45 MHz with 6 V supply, reflecting optimized trade-offs between linearity, noise, and power consumption for VHF receiver applications.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SA604AD/01,118 | Integrates limiter, quadrature detector, and RSSI; no on-board oscillator; 45 MHz IF focused | Targeted at FM demodulation rather than RF mixing; requires external LO source | Select when full IF signal chain (mixer + demodulator) is needed instead of standalone mixer-oscillator |
| NE602N | Same functional block diagram and pinout; manufactured by ON Semiconductor; 2.5 mA typical ICC | Identical use cases and performance specs; qualified for broader temp range (−55 °C to +125 °C) | Choose for extended temperature operation or dual-sourcing where NXP supply continuity is constrained |
Compared with SA602AN/01,112, SA604AD/01,118 shifts focus from RF mixing to IF processing, while NE602N offers identical mixer-oscillator functionality with enhanced thermal ruggedness-making it suitable for military or automotive-adjacent deployments where extended temperature margin is critical.

FAQ
What is the maximum oscillator frequency supported by the SA602AN/01,112?
The SA602AN/01,112 oscillator operates up to 200 MHz in crystal or tuned-tank configurations. Performance depends on tank Q-factor and required drive level; above 100 MHz, adding a 22 kΩ resistor from OSC_E (pin 7) to ground improves startup reliability by increasing oscillator bias current. External LO injection at OSC_B (pin 6) extends usable frequency beyond this limit.
Can the SA602AN/01,112 be used with external LO sources?
Yes, the SA602AN/01,112 supports external LO injection via OSC_B (pin 6) through a DC blocking capacitor. The required signal is ≥200 mVPP, and the internal oscillator must be disabled by omitting crystal/tank components. This configuration maintains full mixer functionality while enabling precise frequency control from a synthesizer or other LO source.
What is the recommended supply voltage range for stable operation of the SA602AN/01,112?
The SA602AN/01,112 operates reliably from 4.5 V to 8.0 V DC. At 6 V, it achieves optimal balance of 2.4 mA typical current draw, 17 dB conversion gain, and <5.0 dB noise figure. Operation at 4.5 V reduces current but degrades IP3i by ~2 dB; operation above 8 V risks permanent damage per absolute maximum ratings.
How does the SA602AN/01,112 handle RF input matching?
The SA602AN/01,112 features internally biased RF inputs (IN_A and IN_B) with an equivalent AC impedance of 1.5 kΩ || 3 pF up to 50 MHz. This allows direct interface with common crystal or ceramic IF filters without external biasing networks or DC return paths, simplifying front-end design and reducing component count.
Is the SA602AN/01,112 pin-compatible with the NE602 series?
Yes, the SA602AN/01,112 shares identical pinout, electrical characteristics, and functional architecture with the NE602 family. Both use the same SO8 (SOT96-1) package and support interchangeable use in existing designs, though SA602AN/01,112 is qualified for −40 °C to +85 °C while NE602N extends to −55 °C to +125 °C.
