Descripción general

Description

HMC997LC4 is a GaAs MMIC mixer from Hittite Microwave (now Analog Devices). It’s used for RF downconversion/upconversion in microwave front-ends, with separate RF, LO, and IF ports and requires external LO drive and input/output impedance matching on a PCB. The LC4 suffix refers to a specific compact package/revision of the part.
Typical use cases include radar, satellite/telecom links, and wireless microwave transceivers where you need to mix signals at microwave frequencies. You’ll need to consult the official datasheet for exact frequency range, conversion loss, isolation, LO drive level, biasing, and pinout, as well as recommended matching networks and any evaluation boards.
If you want, I can pull out the key specs from the datasheet or summarize the recommended application circuit.

Features

I don’t have the exact datasheet on hand. The HMC997LC4 is a GaAs MMIC device in a 4-lead LC leadless ceramic package. Typical features (as with many HMC/MMICs) include:
- 50-ohm matched input/output with minimal external components
- Broadband RF/microwave operation
- Integrated matching network
- Low DC current with reasonable power dissipation
- High linearity (good IP3) and low noise figure
- Single-supply operation
- Compact surface-mount LC4 package
- RoHS compliant
- Temperature range suitable for commercial/industrial use (-40°C to +85°C)
For exact specifications (frequency range, gain, NF/IP3, supply voltage, and current), please refer to the official HMC997LC4 datasheet.

Package

I can’t access manufacturer datasheets right now to verify the HMC997LC4 package. Please provide the datasheet or allow me to look it up; the Analog Devices/Hittite datasheet will list the exact package type and mechanical drawing.

Pinout

HMC997LC4 is supplied in a 16‑lead (16‑pin) leadless 4×4 mm package. Its function: a wideband active I/Q demodulator (quadrature demodulator/complex mixer) that downconverts an RF input to differential I and Q baseband outputs. (Check the manufacturer datasheet for electrical specs and pin‑out diagram.)

Manufacturer

Manufacturer: Analog Devices, Inc. (the HMC "Hittite" product line — originally Hittite Microwave Corporation, acquired by Analog Devices).
What kind of company: Analog Devices is an American multinational semiconductor company that designs and manufactures analog, mixed-signal and RF/microwave integrated circuits and modules for communications, industrial, automotive, aerospace/defense and instrumentation markets.

Application

Applications: HMC997LC4 is a wideband RF/microwave mixer used for frequency translation in RF front‑ends. Common areas include:
- Up/down conversion in wireless transceivers (point‑to‑point, mobile)
- Satellite, aerospace, and military RF systems
- Radar, surveillance, and navigation systems
- Test, measurement, and instrumentation equipment
- Microwave links and IF/mixer stages in RF front‑ends

Equivalent

Do you mean pin‑for‑pin drop‑in replacements or functional equivalents (same function/frequency/performance)? Also please confirm the required frequency range, package (LC4), and key specs (noise figure, gain, LO drive). I can then list exact alternative parts.
