Analog Devices Inc. 117160-HMC604LP3

Overview

117160-HMC604LP3 from Analog Devices (formerly Hittite Microwave) is a GaAs PHEMT MMIC low-noise amplifier with integrated bypass mode, operating from 4.8 to 6.0 GHz. It delivers 15 dB gain, 1.5 dB noise figure, and +26 dBm output IP3 at +5 V/42 mA in LNA mode, and supports ultra-low-power bypass operation (<10 µA), making it suitable for WiMAX and C-band radio receiver front-ends requiring dynamic RF path control.

For engineers reviewing the 117160-HMC604LP3 datasheet, 117160-HMC604LP3 pinout, 117160-HMC604LP3 application, or 117160-HMC604LP3 equivalent, key selection considerations include its dual-mode LNA/bypass functionality, 50 Ω matched I/O, 3×3 mm QFN package, temperature-stable gain/noise performance, and compatibility with +3 V or +5 V single-supply operation.

Technical Context

The 117160-HMC604LP3 integrates a monolithic GaAs PHEMT amplifier core with an on-die passive bypass path, enabling seamless RF signal routing without external switches. Its control logic uses a single Vctl pin (0 V / Vdd) to select between active amplification and low-loss insertion mode, with sub-100 ns switching speed.

In LNA mode, the device achieves 12–15 dB small-signal gain across 4.8–6.0 GHz with input/output return loss ≥12 dB, while maintaining 1.5–2.1 dB noise figure and +24 to +26 dBm IP3. In bypass mode, insertion loss is –2 to –3 dB with >20 dB return loss and <10 µA supply current - all without external matching components.

FAQ

What is the primary function of the 117160-HMC604LP3 in an RF signal chain?

The 117160-HMC604LP3 serves as a dual-mode GaAs MMIC low-noise amplifier with integrated bypass path. In LNA mode, it provides 15 dB gain and 1.5 dB noise figure for sensitive receive paths; in bypass mode, it routes RF signals with –2.5 dB loss and <10 µA current, enabling power-efficient TDD or fault-tolerant architectures. Its 50 Ω matched I/O simplifies integration without external matching.

Does the 117160-HMC604LP3 require external matching components?

No, the 117160-HMC604LP3 features internally matched 50 Ω input and output ports across 4.8–6.0 GHz in both LNA and bypass modes. The datasheet confirms ≥12 dB input return loss and ≥14 dB output return loss with no external matching required - only DC blocking capacitors and supply bypassing (100 pF and 10 nF) are needed per the application circuit.

What supply voltage options does the 117160-HMC604LP3 support?

The 117160-HMC604LP3 operates from a single positive supply ranging from +2.7 V to +5.5 V. Performance is characterized at +3 V and +5 V: at +5 V, it delivers 15 dB gain and +26 dBm IP3; at +3 V, gain is 12.5 dB and IP3 is +23 dBm. Supply current scales linearly (17 mA @ +3 V, 42 mA @ +5 V), supporting flexible power system design.

How is mode selection implemented on the 117160-HMC604LP3?

Mode selection on the 117160-HMC604LP3 is controlled via the Vctl pin (Pin 16): applying Vdd selects LNA mode; grounding Vctl (0 V) activates bypass mode. The truth table confirms this binary control, and switching speeds are 7 ns (LNA→bypass) and 150 ns (bypass→LNA). No pull-up/pull-down resistors are required - drive strength matches standard CMOS logic levels.

What package type and thermal characteristics apply to the 117160-HMC604LP3?

The 117160-HMC60LP3 uses a 16-lead 3×3 mm QFN package with exposed thermal paddle. Its thermal resistance (θ_jc) is 76.9 °C/W, and maximum continuous power dissipation is 850 mW at 85 °C (derating 13 mW/°C above). The package is MSL1 rated, with Sn/Pb lead finish and max reflow temperature of 235 °C - all documented in the official Hittite outline drawing and package information sheet.
