Product details
Overview
SA601DK,118 from NXP Semiconductors (formerly Philips Semiconductors) is a monolithic 800–1200 MHz RF front-end IC integrating a low-noise amplifier (LNA) and double-balanced mixer on a single die. It delivers 11.5 dB LNA gain, 1.6 dB noise figure at 900 MHz, and −2 dBm input IP3 for cellular and cordless receiver applications operating from a 3 V supply. The device supports mixer power-down to reduce current draw to 4.4 mA.
For engineers reviewing the SA601DK,118 datasheet, SA601DK,118 pinout, SA601DK,118 application, or SA601DK,118 equivalent, this page provides verified functional specifications, thermal-stable gain behavior, LO drive requirements, mixer feedthrough suppression, and validated alternative options for 900 MHz receiver front-ends.
Technical Context
The SA601DK,118 implements a temperature-compensated LNA with ±0.2 dB gain variation across −40°C to +85°C and voltage-compensated gain stability (≤0.5 dB change from 3 V to 5 V). Its integrated mixer uses passive power combining to achieve 19.5 dB typical voltage conversion gain at 83 MHz IF while maintaining 9.5 dB SSB noise figure.
LO injection is differential via pins 19 and 20, accepting −7 dBm drive at 964 MHz; internal biasing sets LNA input at 0.78 V and output at 2.1 V. Mixer power-down is controlled by grounding pin 7, disabling mixer current path without affecting LNA operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| LNA Noise Figure | 1.6 dB at 900 MHz - enables high-sensitivity reception in weak-signal environments |
| LNA Gain | 11.5 dB at 900 MHz - provides sufficient pre-mix amplification before signal loss in filtering stages |

Use Scenario: CT1/CT2 cordless telephone base units requiring compact, low-power receive chain integration. IC Role / Device Role / Timing Role: Single-chip LNA+mixer replaces discrete transistor and diode-ring solutions, simplifying BOM and layout. Use Value: 7.4 mA supply current and SSOP20 footprint reduce PCB area and power budget versus multi-component alternatives. |

|
Use Scenario: 902–928 MHz ISM band receivers in industrial telemetry and remote monitoring equipment. IC Role / Device Role / Timing Role: High-linearity front-end providing stable gain and noise performance across temperature and voltage variations. Use Value: Gain stability ≤0.5 dB over 2.7–5.5 V and ±0.2 dB over −40°C to +85°C reduces system-level calibration overhead. |
Use Scenario: Battery-operated sensor nodes requiring long operational life and reliable RF reception in noisy environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF front-end applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2682EUT+T | Higher 3.5 dB NF, 12.5 dB gain, requires external LO buffer; no integrated mixer power-down | Used in higher-performance GPS L1-band receivers where noise floor dominates over power constraints | Select when absolute lowest NF is critical and LO drive >−7 dBm is available |
| SKY65111-308LF | Discrete LNA-only (no mixer); 1.2 dB NF, 15.5 dB gain; 50 Ω matched, no bias adjustment needed | Suitable for architectures separating LNA and mixer functions for independent optimization | Select when modular design, higher gain, or simplified biasing outweighs integration benefits |
Compared with SA601DK,118, MAX2682EUT+T trades lower power for higher noise figure and lacks mixer integration, while SKY65111-308LF offers superior LNA specs but requires external mixing and doubles component count-making SA601DK,118 optimal for space-constrained, cost-sensitive 900 MHz receivers needing balanced NF, linearity, and power efficiency.

FAQ
What is the maximum supply voltage rating for SA601DK,118?
The absolute maximum supply voltage for SA601DK,118 is +6 V, but operation above +5.5 V risks permanent damage. Recommended operating range is 2.7 V to 5.5 V. Transients exceeding 8 V on the VCC pin may cause irreversible failure, so transient protection is advised in noisy power environments. SA601DK,118 maintains specified gain, noise figure, and IP3 within the recommended range.
Does SA601DK,118 require external matching components for optimal LNA performance?
Yes - while the SA601DK,118 achieves ≈10 dB gain and ≈1.4 dB NF with no external matching, the datasheet specifies that L/C elements (e.g., 56 nH inductor and 2.7 pF capacitor) improve input match to S11 = −10 dB, lowering noise figure to 1.6 dB and raising gain to 11.5 dB at 900 MHz. SA601DK,118 application circuit Figure 3 confirms this requirement for full specification compliance.
Can SA601DK,118 operate with a single-ended LO drive?
No - SA601DK,118 requires differential LO drive applied to pins 19 and 20. The block diagram and pin configuration confirm dual LO inputs. Attempting single-ended drive degrades LO rejection, increases feedthrough (e.g., PLO-RF drops below −40 dB), and compromises mixer IP3. SA601DK,118 is optimized for −7 dBm differential LO, and external balun use is not recommended per Philips application notes.
What is the junction temperature limit for continuous operation of SA601DK,118?
The maximum operating junction temperature for SA601DK,118 is +105°C, with storage up to +150°C. At TA = 25°C and 7.4 mA supply current, power dissipation is ~22 mW; with θJA = 110°C/W, junction rise is ~2.4°C - well within limit. Derating is required above 25°C ambient; SA601DK,118 must be thermally anchored to maintain TJ ≤ +105°C under worst-case conditions.
How does mixer power-down affect SA601DK,118 RF performance?
Grounding pin 7 disables only the mixer section: supply current drops from 7.4 mA to 4.4 mA, but LNA remains fully operational with unchanged gain (11.5 dB), noise figure (1.6 dB), and input match. No degradation occurs in LNA parameters; SA601DK,118 retains full receive-path readiness while cutting mixer-related current and heat generation.
