Description
The 103 is MMIC Buffer Amplifier. A Monolithic Microwave Integrated Circuit (MMIC) buffer amplifier is a type of amplifier that is designed to operate at microwave and millimeter-wave frequencies. MMICs are integrated circuits that are specifically engineered for high-frequency applications, typically in the microwave (300 MHz to 300 GHz) and millimeter-wave (30 GHz to 300 GHz) frequency ranges. These amplifiers are commonly used in various applications, including radar systems, satellite communications, microwave radios, and more.
The STB7102, STB7103 and STB7104 designed for Mobile Phone applications (0.1/2.5GHz), are an high isolation Si MMIC Buffer Amplifiers. Manufactured in the third generation of ST proprietary bipolar process, they offers an excellent isolation and a good linearity using a low current consumption.
These low current amplifiers operate on 3.0 V. The STB710x family is housed in an ultra miniature package SOT323-6L surface mount package. SOT323-6L dimensions are 1.15mmx1.8mm with 0.8 mm thickness.
