Product Description
The RF2048 is a general purpose, low cost RF amplifier
IC. The device is manufactured on an advanced Gallium
Arsenide Heterojunction Bipolar Transistor (HBT) pro-
cess, and has been designed for use as an easily-cas-
cadable 50鈩?gain block. Applications include IF and RF
amplification in wireless voice and data communication
products operating in frequency bands up to 8000MHz.
The device is self-contained with 50鈩?input and output
impedances and requires only two external DC biasing
elements to operate as specified. With a goal of
enhanced reliability, the extremely small Micro-X ceramic
package offers significantly lower thermal resistance than
similar size plastic packages.
