General Description
The HMC863ALC4 is a three stage GaAs pHEMT
MMIC 1/2 Watt Power Amplifier which operates
between 24 and 29.5 GHz. The HMC863ALC4 pro-
vides 24 dB of gain, +28.5 dBm of saturated output
power and 22.5% PAE from a +5.5V supply. High
output IP3 makes the HMC863ALC4 ideal for point-to-
point and point-to-multi-point radio systems as well as
VSAT applications. The RF I/Os are DC blocked and
matched to 50 Ohms for ease of integration into higher
level assemblies. The HMC863ALC4 can be operated
over a Vdd range of +4.0 to +6.0V.
