Analog Devices Inc. 128383-HMC916LP3E

Overview

HMC916LP3E from Analog Devices (formerly Hittite Microwave) is an active x3 frequency multiplier MMIC in a 3×3 mm leadless QFN package, operating with 8–16 GHz RF output and 2.66–5.33 GHz input. It delivers 2 dBm typical output power from a single +5 V supply at 83 mA, achieves >15 dBc spurious suppression, and exhibits –152 dBc/Hz SSB phase noise at 100 kHz offset - ideal for LO multiplier chains in microwave radios and radar systems.

For engineers reviewing the HMC916LP3E datasheet, HMC916LP3E pinout, HMC916LP3E application, or HMC916LP3E equivalent, this page provides verified technical context, validated pin functions, confirmed RF performance metrics across temperature and supply voltage, and real-world use cases in military, test instrumentation, and satellite communication systems.

Technical Context

The HMC916LP3E implements a monolithic GaAs-based active tripler architecture optimized for differential or single-ended operation. Its RF input (pins 2 & 3) and output (pins 10 & 11) are AC-coupled and 50 Ω matched, enabling direct integration into high-frequency signal paths without external matching networks.

It operates over –40 °C to +85 °C with thermal resistance of 39.5 °C/W (junction-to-ground paddle), and maintains stable output power (±0.5 dB) across input drive (0–10 dBm), supply voltage (4.75–5.25 V), and temperature - critical for phase-sensitive LO generation in coherent radar and VSAT transceivers.

Key Specifications

Pinout & Package

Package: 16-lead 3×3 mm leadless QFN (RoHS-compliant, MSL1, exposed ground paddle). All GND pins (1, 4–9, 12, 13, 15, 16) and the exposed paddle must be soldered to PCB RF/DC ground per Hittite land pattern guidelines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar frequency multiplier applications.

Compared with HMC1085LP3E and HMC1117LP3E, the HMC916LP3E uniquely balances 8–16 GHz coverage, 2 dBm output, and –152 dBc/Hz phase noise - making it the optimal choice for X/Ku-band LO chains where spectral purity and output stability are prioritized over maximum frequency extension or raw power.

Manufacturer

Analog Devices acquired Hittite Microwave in 2014, integrating its high-frequency RF MMIC portfolio into ADI's broader RF & Microwave division focused on defense, aerospace, and instrumentation markets.

The HMC916LP3E belongs to Hittite's legacy SMT MMIC frequency multiplier family, engineered specifically for high-efficiency, low-phase-noise LO generation in compact, thermally constrained microwave subsystems.

FAQ

What is the recommended DC decoupling for HMC916LP3E?

HMC916LP3E requires three-stage decoupling on the Vcc pin (pin 14): a 100 pF capacitor (high-frequency bypass), a 1000 pF capacitor (mid-frequency stabilization), and a 4.7 µF capacitor (low-frequency reservoir), all placed as close as possible to the package per the 128702 evaluation board layout. This configuration suppresses supply-induced phase noise and prevents oscillation across the 8–16 GHz band.

Can HMC916LP3E operate in single-ended mode?

Yes, HMC916LP3E supports single-ended operation: pin 2 (RFNIN) must be grounded, pin 11 (RFNOUT) terminated in 50 Ω, and pins 3 (RFIN) and 10 (RFOUT) used as the sole RF input and output. Input return loss remains ≥13 dB and output return loss ≥15 dB across the full 8–16 GHz output band in this configuration.

What is the maximum input power rating for HMC916LP3E?

The absolute maximum RF input power for HMC916LP3E is +20 dBm, as specified in the Absolute Maximum Ratings table. However, electrical specifications are guaranteed only for input power between 0 and +10 dBm; operation above +10 dBm may cause compression or degradation in spurious suppression without damage.

Is HMC916LP3E still in active production?

HMC916LP3E is marked "OBSOLETE" in the provided documentation, indicating end-of-life status by Analog Devices. Aetrix Electronics maintains legacy inventory and offers lifecycle management support, including last-time buy coordination and cross-reference assistance for qualified replacements such as HMC1085LP3E.

How does thermal performance affect HMC916LP3E output power?

HMC916LP3E output power varies by ≤0.5 dB over –40 °C to +85 °C when mounted per spec (exposed paddle soldered to solid ground plane). At +85 °C, junction temperature reaches 101.4 °C (nominal) with 39.5 °C/W thermal resistance - confirming stable RF performance without derating under full-load conditions.
