1) Measurement conditions are as follows: T = 25

2) S11 & S22 can be improved, at a specific frequency, by moving an input shunt capacitor (C2) along an input transmission line.

3) OIP3 is measured with two tones at an output power of +8 dBm/tone separated by 1 MHz.

SOT-89 Surface Mount Package

The ASG304 is designed for high linearity, high

gain, and low noise over a wide range of fre-

quency, being suitable for use in both receiver

and transmitter of wireless and wireline telecom-

munication systems. The product is manufactured

using a state-of-the-art SiGe HBT process of the

company's own, making it cost-effective and

highly reliable. The amplifiers are available in a

low cost SOT-89 package completing stringent

DC and RF tests.
