HMC1018LP4E

HMC1018LP4E is a GaAs MMIC microwave device from Hittite (now Analog Devices) designed for 10–18 GHz operation, housed in a compact four-lead leadless package (LP4E). It serves as a front-end RF block (used in amplifier or mixer chains) for microwave links, radar, and SATCOM. Like other MMICs, it requires external biasing and RF matching per the datasheet. For exact specs (gain, noise figure, IP3, supply/bias currents, and packaging details), see the official Analog Devices datasheet.

I don’t have a live cross-reference database. To locate equivalents, confirm HMC1018LP4E’s function and specs (e.g., RF MMIC LNA/PA/mixer or switch, frequency range, package). Then use Analog Devices’ Cross Reference tool or distributor catalogs (DigiKey/Mouser) to find parts with the same pinout and similar NF, gain, and bias. Consider other RF MMIC families from ADI, MACOM, and Mini-Circuits in the same GHz range, and verify footprint and biasing before substituting.

- Pin count: 4 pins (leadless 4-lead package)
- Function: GaAs MMIC RF amplifier (low-noise/LNA) for RF front-end applications.

Manufacturer: Analog Devices, Inc. (the HMC1018LP4E originated from Hittite Microwave, which Analog Devices acquired).
What kind of company: Analog Devices is a global semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits, including RF/microwave components used in communications, defense, aerospace, automotive, and consumer electronics.

Applications of HMC1018LP4E include:
- Wideband RF front-end LNA for receiver chains
- Satellite communications/VSAT receiver front-ends
- Radar and surveillance systems
- Wireless backhaul and point-to-point links
- Military/aerospace RF subsystems and avionics
- Test and measurement equipment RF front-ends (spectrum analyzers, signal generators)
- General microwave/millimeter-wave front ends in integrated modules
(Used in broadband microwave/millimeter-wave RF systems requiring low noise and wide bandwidth.)

Package type: 4-lead plastic leadframe (LP4) surface-mount RF package.
