Product Overview
The HMC625BLP5ETR is a broadband 6-bit GaAs MMIC digital variable gain amplifier engineered by Analog Devices Inc. (formerly Hittite Microwave Corporation) for precise RF signal amplitude adjustment across wireless and test systems. Operating over DC up to 5.0 GHz, this monolithic IC delivers a full 31.5 dB tuning span, covering -13.5 dB attenuation through +18 dB gain with fixed 0.5 dB Least Significant Bit resolution. Built with GaAs MESFET process, the device maintains stable gain accuracy and high output linearity with typical +32 dBm OIP3, minimizing signal distortion under multi-carrier operation. It supports three control schemes: direct parallel, latched parallel and 3-wire serial SPI with serial output for multi-device cascading, plus user-configurable power-up gain state. Packaged in compact QFN-32(5.00mm x 5.00mm x 0.90mm) SMD housing, the serves as integrated gain/attenuation control block for cellular communication, microwave backhaul, test measurement and EW radar hardware.
Core Advantages
Ultra-Wideband Continuous Performance
Provides consistent gain and attenuation response across DC to 5.0 GHz single-chip bandwidth, covering mainstream cellular, microwave and test frequency bands to simplify BOM and component stocking.
High Gain Tuning Precision & 0.5dB Step Resolution
6-bit digital tuning delivers full 31.5 dB adjustment range with tight 0.5 dB LSB steps, typical step error ±0.25 dB, ensuring flat amplitude response across full operating spectrum.
High Output Linearity for Multi-Carrier Systems
Typical output third-order intercept (OIP3) reaches +32 dBm, preserving clean undistorted RF signals under high-power multi-carrier operation for base station and radio transceiver hardware.
Triple Control Interface with Cascading Support
Compatible with latched/direct 6-bit parallel logic and 3-wire serial SPI; serial data output pin enables seamless cascading of multiple Hittite serial-controlled RF ICs, plus customizable power-up gain state.

Frequently Asked Questions
Q1: Is your currently available stock of the HMC625BLP5ETR variable gain amplifier 100% genuine and original?
A: Yes, we guarantee that all HMC625BLP5ETR devices in our warehouse are 100% brand-new, factory-original products from Analog Devices Inc. (ADI). They are stored in climate-controlled environments and handled strictly following standard anti-static ESD safety measures.
Q2: What is the significance of the “TR” suffix in the part number HMC625BLP5ETR?
A: The “TR” suffix specifies that the components are delivered in Tape and Reel format. This packaging is factory-configured for high-speed automated SMD pick-and-place placement on manufacturing assembly lines.
Q3: How do you select between the parallel and serial control modes on this VGA chip?
A: Control interface mode is determined via dedicated P/S logic pin. Pull P/S pin HIGH to enable 3-wire serial SPI mode; pull P/S pin LOW to activate direct/latched 6-bit parallel input mode.
Q4: How can our engineering layout division request scattering parameters (S-parameters), EVB designs, or bulk volume pricing tiers?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
