Product details
Overview
SA602AD/01,118 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, −13 dBm input third-order intercept, and operates from 4.5 V to 8.0 V supply with 2.4 mA typical current draw. It is designed for cellular radio front-ends requiring compact, low-power RF frequency conversion.
For engineers reviewing the SA602AD/01,118 datasheet, SA602AD/01,118 pinout, SA602AD/01,118 application, or SA602AD/01,118 equivalent, this page provides verified circuit role, SO8 package mapping, Gilbert-cell architecture details, oscillator configuration options (crystal/tank/external LO), and real-world design constraints including internal biasing, 1.5 kΩ RF input impedance, and 200 MHz max oscillator frequency.
Technical Context
The SA602AD/01,118 implements a Gilbert-cell multiplier topology with differential RF inputs (IN_A/IN_B) and balanced mixer outputs (OUT_A/OUT_B), enabling high linearity and noise performance. Its oscillator section supports crystal, tuned tank, or external LO injection via OSC_B (pin 6), with OSC_E (pin 7) providing emitter output for buffered operation.
Internally biased RF ports eliminate external DC blocking for IN_A/IN_B and OUT_A/OUT_B, while maintaining ~1.5 kΩ || 3 pF AC input impedance up to 50 MHz. The voltage regulator ensures stable core bias across −40 °C to +85 °C ambient, supporting battery-powered portable radios and VHF transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
SA602AD/01,118 is housed in an 8-lead SO (SO8, SOT96-1) surface-mount package with 3.9 mm body width and standard pitch. Pin layout follows JEDEC MS-012AC, optimized for RF layout isolation and thermal dissipation in compact PCB designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN_A) | RF input A | Differential RF port; internally biased; interchangeable with IN_B but not for external DC biasing |
| 2 (IN_B) | RF input B | Differential RF port; symmetrical to IN_A; forms balanced input pair for second-order harmonic rejection |
| 3 (GND) | Ground | Analog ground reference for mixer core, oscillator, and regulator; requires low-inductance PCB connection |
| 4 (OUT_A) | Mixer output A | Active-balanced IF output; internally pulled up with 1.5 kΩ resistor; supports single-ended or balanced termination |
| 5 (OUT_B) | Mixer output B | Complementary IF output; paired with OUT_A for differential IF filtering or transformer coupling |
| 6 (OSC_B) | Oscillator base | LO injection point for external local oscillator; accepts ≥200 mVPP signal via DC-blocking capacitor |
| 7 (OSC_E) | Oscillator emitter | Buffered oscillator output; used as crystal/tank feedback node or LO source for downstream stages |
| 8 (VCC) | Supply voltage | Single 4.5–8.0 V rail powering all internal blocks; requires local 6.8 μF decoupling per datasheet layout |
Key Features
| Feature | Design Value |
|---|---|
| Gilbert-cell mixer core | Delivers 17 dB conversion gain and −13 dBm IP3 simultaneously, enabling high sensitivity without sacrificing dynamic range |
| Integrated oscillator/buffer | Supports crystal, LC tank, or external LO drive-eliminates discrete transistor oscillator stage and reduces BOM count by ≥3 components |
| Internal bias network | Removes need for external DC blocking on all RF ports, simplifying filter interface and improving repeatability in volume production |
| Low-power operation | 2.4 mA typical supply current at 6 V allows >100-hour battery life in AA-powered portable radios |
| VHF frequency capability | Validated operation to 200 MHz oscillator and 500 MHz RF input enables use in 136–174 MHz land-mobile radio bands |

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer and oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SA612AD/01,118 | Higher 3.5 mA supply current; improved 4.5 dB NF at 45 MHz; identical SO8 pinout and oscillator architecture | Better noise performance suits ultra-low-SNR instrumentation; higher current limits battery-life-critical portable use | Select SA612AD/01,118 when NF <4.7 dB is mandatory and power budget allows +1.1 mA overhead |
| NE602N | DIP-8 through-hole package; same electrical specs but no SO8 footprint; obsolete per NXP discontinuation notice | Legacy repair only; incompatible with modern SMT assembly lines and high-density RF layouts | Choose SA602AD/01,118 for new designs requiring RoHS-compliant, reflow-solderable SO8 packaging and active manufacturing support |
Compared with SA612AD/01,118, the SA602AD/01,118 trades 0.2 dB NF for 1.1 mA lower supply current-critical for multi-year battery deployments. Versus NE602N, it provides identical RF performance in a manufacturable SO8 package with full lifecycle support, eliminating obsolescence risk in production programs.

FAQ
What is the maximum oscillator frequency supported by the SA602AD/01,118?
The SA602AD/01,118 oscillator operates reliably up to 200 MHz in crystal or tuned tank configurations, as confirmed in Table 7 of the NXP datasheet. Performance beyond this limit depends on external tank Q-factor and drive level; for frequencies above 200 MHz, external LO injection via OSC_B (pin 6) is required. The SA602AD/01,118 itself does not guarantee oscillation stability or phase noise above 200 MHz.
Can the SA602AD/01,118 be used with a 50 Ω RF source without external matching?
No-the SA602AD/01,118 presents ~1.5 kΩ || 3 pF input impedance at IN_A/IN_B pins, not 50 Ω. Direct 50 Ω connection causes severe mismatch loss and degraded noise figure. A broadband matching network (e.g., shunt capacitor + series inductor) or balun is required to transform 50 Ω to the device's optimal input impedance, as shown in Figure 4a of the SA602AD/01,118 datasheet.
Does the SA602AD/01,118 require external DC blocking capacitors on its RF ports?
No-IN_A, IN_B, OUT_A, and OUT_B pins are internally DC-biased, so external DC blocking capacitors are unnecessary and discouraged. Adding them would disrupt the internal bias network and degrade conversion gain and noise figure. Only OSC_B (pin 6) requires a DC-blocking capacitor when driven by an external LO, per Figure 6 and Section 7 of the datasheet.
What is the recommended supply decoupling for the SA602AD/01,118?
NXP specifies a 6.8 μF tantalum or low-ESR electrolytic capacitor directly at the VCC (pin 8) pad, supplemented by a 100 nF ceramic capacitor in parallel. This dual-capacitor approach suppresses both low-frequency ripple and high-frequency switching noise from the internal oscillator and mixer stages, preventing LO pulling and gain instability-details are in Figure 8 and Section 14 of the SA602AD/01,118 datasheet.
Is the SA602AD/01,118 pin-compatible with the legacy NE602?
Yes-the SA602AD/01,118 shares identical pin functions and electrical characteristics with the NE602, but in an SO8 (SOT96-1) package instead of DIP-8. Pin mapping is 1:1: IN_A (1), IN_B (2), GND (3), OUT_A (4), OUT_B (5), OSC_B (6), OSC_E (7), VCC (8). However, the SA602AD/01,118 is not a drop-in replacement for NE602 in through-hole designs due to package incompatibility.
