Sirenza Microdevices’ CGB-1089Z is a high performance InGaP HBT MMIC
amplifier utilizing a Darlington configuration with a 75 ohm active bias
network. The active bias network provides stable current over temperature
and process Beta variations. Designed to run directly from a 5V supply, the
CGB-1089Z does not require a dropping resistor as compared to typical
Darlington amplifiers. The CGB-1089Z product is designed for high linearity
5V gain block applications that require small size and minimal external
components. It is internally matched to 75 ohms.

Operation of this device beyond any one of these limits m ay cause
permanent damage. For reliable continuous operation, the device
voltage and current m ust not exceed the m aximum operating
values specified in the table on page one.
Bias Conditions should also satisfy the following expression:
IDVD < (TJ - TL) / RTH, j-l TL=TLEAD
Appropriate precautions in handling, packaging and testing
devices must be observed.

Mounting Instructions
1. Solder the copper pad on the backside of the device package to
the ground plane.
2. Use a large ground pad area with many plated through-holes as
shown.
3. We recommend 1 or 2 ounce copper. Measurement for this
datasheet were made on a 60 mil thick GTEK board with 1
ounce copper on both sides.
