CGB-1089Z
50MHz to 1000MHz SINGLE ENDED
InGaP/GaAs HBT MMIC CATV AMPLIFIER
RFMD’s CGB-1089Z is a high performance InGaP HBT MMIC amplifier uti-
lizing a Darlington configuration with a 75Ω 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 compo-
nents. It is internally matched to 75Ω.

Pin Function Description
1RF IN
RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation.
2, 4 GND Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possi-
ble.
3RF OUT/BIAS
RF output and bias pin. DC voltage is present on this pin, therefore a DC blocking capacitor is necessary for proper oper-
ation.

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.
