SA5219D Description

Short technical summary and product information.

The SA5219D from Philips is a monolithic wideband variable gain amplifier (VGA) that utilizes a high-speed bipolar process and the Gilbert architecture. This device is designed for linear RF applications, with its gain controlled by a single DC voltage.

Key features include a 700MHz bandwidth, high impedance differential inputs (1kΩ), and a 50Ω differential output. The amplifier operates from a single 5V supply, consuming only 40mA. It provides a gain control range of over 60dB at 200MHz and a maximum differential gain of 26dB. The exceptional linearity between control voltage and gain, along with a minimum noise figure of 7dB, makes it suitable for demanding applications.

The SA5219D can perform AGC, impedance transformation, and balun functions simultaneously. Its design allows for excellent dynamic range across various gain settings and maintains good noise performance even at reduced gain, which is crucial for linear AGC systems.

Available in 16-pin DIP and SOIC packages, the SA5219D is suitable for surface mount or through-hole assembly. Its applications span linear AGC systems, AM modulators, RF baluns, cable TV amplifiers, fiber optic AGC, RADAR, and cellular communications.
