HMC-ALH445 Information

Description

Here's a concise introduction to the HMC-ALH445: The HMC-ALH445 from Analog Devices is a Gallium Arsenide (GaAs) High Electron Mobility Transistor (HEMT)-based wideband low noise amplifier (LNA), operating in the W-band frequency range of 18-40 GHz. This die-packaged LNA boasts excellent performance metrics, including a noise figure of 3.9 dB at 28 GHz, gain of 9 dB, and P1dB output power of +12 dBm at 28 GHz. It requires a supply voltage of +5V at 45 mA. The HMC-ALH445 is designed to support various applications that require high-frequency amplification with low noise figures, such as wideband communication systems, point-to-point and point-to-multipoint radios, military and space communications, and test instrumentation. With its compact size (1.6 x 1.6 x 0.1 mm) and robust performance, this LNA is an excellent choice for a range of wireless infrastructure and defense-related applications.

Features

The HMC-ALH445 features:

Noise Figure: 3.9 dB @ 28 GHz
Gain: 9 dB
P1dB Output Power: +12 dBm @ 28 GHz
Supply Voltage: +5V @ 45 mA
Die Size: 1.6 x 1.6 x 0.1 mm

It is an RF amplifier with a GaAs HEMT process, operating in the W-band frequency range (18-40 GHz). It has low noise figure and high gain, making it suitable for wideband communication systems, point-to-point radios, point-to-multi-point radios, military & space applications, and test instrumentation.

Package

The package type of HMC-ALH445 is Die-4.

Pinout

Unfortunately, the product information provided does not mention the pin count or function of the HMC-ALH445. The package type is listed as "Die-4", which typically means that the component is available in a wire-bondable die form rather than a packaged IC with pins. As the category and parameter sections are blank, it appears that this information is not provided by the manufacturer. It's possible to contact Analog Devices or consult their product documentation for more details on the pin count and function of the HMC-ALH445.

Manufacturer

The manufacturer of the HMC-ALH445 is Analog Devices, a fabless semiconductor company that designs and manufactures analog, digital, and mixed-signal integrated circuits (ICs) used in various industries such as automotive, industrial, medical, and consumer electronics.
