Product details
Overview
HMC772LC4 from Analog Devices (formerly Hittite Microwave) is a GaAs HEMT MMIC low-noise amplifier operating from 2 to 12 GHz, delivering 15 dB small-signal gain, 1.8 dB noise figure, +13 dBm P1dB output power, and +25 dBm output IP3 at +4 V / 45 mA supply. It serves as an RF front-end LNA or LO driver in microwave radios and instrumentation.
For engineers reviewing the HMC772LC4 datasheet, HMC772LC4 pinout, HMC772LC4 application, or HMC772LC4 equivalent, key selection criteria include its wideband 2–12 GHz operation, internal 50 Ω input/output matching, DC-blocked I/Os, RoHS-compliant 4×4 mm ceramic QFN package, and suitability for high-reliability SMT-based microwave systems requiring stable noise and linearity performance.
Technical Context
The HMC772LC4 employs a monolithic GaAs HEMT process with integrated bias network and on-chip impedance matching, enabling broadband operation without external matching components. Its I/O ports are AC-coupled and internally matched to 50 Ω, simplifying integration into 50 Ω RF signal chains.
It operates with fixed +4 V drain supply and adjustable gate voltage (–1 to +0.3 V) to set nominal 45 mA quiescent current. The device supports –40 °C to +85 °C operating temperature range and features thermal resistance of 172 °C/W from channel to ground paddle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 2–12 GHz - enables single-LNA coverage across S-, C-, X-, and Ku-band systems without band switching. |
| Small-Signal Gain | 15 dB typical - provides sufficient amplification before mixer or ADC stages in receiver front-ends. |
| Noise Figure | 1.8 dB typical up to 12 GHz - ensures minimal degradation of system noise floor in sensitive receivers. |
| OIP3 | +25 dBm - supports high dynamic range in crowded spectral environments such as point-to-point radios. |
| P1dB Output Power | +13 dBm - allows use as LO driver for balanced mixers including Hittite's image-reject and I/Q types. |
| Supply Current | 45 mA @ +4 V - enables low-power, thermally manageable operation in compact RF modules. |
| Input/Output Match | 50 Ω DC-blocked - eliminates need for external DC blocking capacitors or impedance-matching networks. |
Pinout & Package
Package: 24-lead leadless ceramic QFN, 4×4 mm body, alumina substrate, gold-over-nickel plating, MSL3, with exposed ground paddle requiring solder connection to PCB RF ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4–7, 12–15, 17–19, 24 | GND | RF/DC ground terminals - must be soldered directly to PCB ground plane with multiple vias for low-inductance return path. |
| 3 | RFIN | AC-coupled 50 Ω RF input - accepts broadband signal without external DC blocking or matching. |
| 8 | Vgg | Adjustable gate bias terminal - sets quiescent current via external voltage source (–1 to +0.3 V). |
| 9 | Vdd | +4 V drain supply input - requires local decoupling per application circuit (C1/C2/C3). |
| 10, 11, 20–23 | N/C | No internal connection - externally grounded per evaluation board layout to maintain RF symmetry and shielding. |
| 16 | RFOUT | AC-coupled 50 Ω RF output - delivers amplified signal with minimal group delay variation across 2–12 GHz. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic GaAs HEMT Process | Enables consistent high-frequency performance and reliability across temperature and unit-to-unit variation. |
| Internally Matched 50 Ω I/O | Reduces bill-of-materials and layout complexity by eliminating discrete matching networks and DC blocks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1099LP3E | Wider bandwidth (0.01–20 GHz), higher NF (2.2 dB typ.), lower gain (12 dB), same 4×4 mm QFN package. | Better ultra-wideband coverage but trades off noise and gain; suited for lab instrumentation over narrowband comms. | Select when sub-2 GHz or >12 GHz extension is required and 0.4 dB NF penalty is acceptable. |
| QPL9547 | SiGe process, 0.6–6 GHz range, 0.65 dB NF, 15.5 dB gain, +21.5 dBm OIP3, 2×2 mm DFN package. | Lower frequency limit and narrower band; optimized for 5G FR1 and WiFi 6E infrastructure, not Ku-band. | Choose for cost-sensitive, lower-frequency consumer or enterprise wireless designs where size and NF are critical. |
Compared with HMC1099LP3E and QPL9547, the HMC772LC4 uniquely balances 2–12 GHz bandwidth, 1.8 dB NF, and +25 dBm OIP3 in a thermally robust ceramic QFN-making it optimal for military, test equipment, and high-end point-to-point radio LNA stages where wideband linearity and noise stability are non-negotiable.

FAQ
What is the operating frequency range of the HMC772LC4?
The HMC772LC4 operates from 2 GHz to 12 GHz, covering S-, C-, X-, and lower Ku-bands. This range is verified across temperature and supply conditions per its datasheet specifications, and the device maintains 15 dB gain and ≤2.5 dB noise figure across the full band at +25 °C.
Does the HMC772LC4 require external matching components?
No, the HMC772LC4 features internally matched 50 Ω input and output ports with AC coupling, eliminating the need for external matching networks or DC blocking capacitors in standard 50 Ω systems. External biasing components (e.g., decoupling caps) are still required per the application circuit.
What is the recommended gate bias voltage for the HMC772LC4?
The HMC772LC4 requires gate bias (Vgg) between –1 V and +0.3 V to achieve the nominal 45 mA supply current at +4 V drain voltage. Typical Vgg is –0.2 V, and adjustment within this range allows fine-tuning of quiescent current and associated linearity/noise trade-offs.
Can the HMC772LC4 be used as an LO driver?
Yes, the HMC772LC4 can serve as an LO driver due to its +15 dBm Psat output power and broadband flat gain, making it compatible with many of Hittite's balanced, I/Q, and image-reject mixers. Its +25 dBm OIP3 ensures minimal LO harmonic distortion and spurious generation.
What package type and thermal considerations apply to the HMC772LC4?
The HMC772LC4 uses a 24-lead 4×4 mm ceramic QFN with exposed ground paddle. Its thermal resistance is 172 °C/W (channel to ground paddle), requiring direct soldering of all GND pins and the paddle to a multilayer PCB ground plane with ample thermal vias to sustain +13 dBm output power reliably.
