Functional Diagram
General Description
The HMC498 is a high dynamic range GaAs
PHEMT MMIC Power Amplifier which operates
between 17 and 24 GHz. The HMC498 provides
24 dB of gain, +27 dBm of saturated power and
25% PAE from a +5.0 V supply voltage. The
HMC498 amplifier can easily be integrated into
Multi-Chip-Modules (MCMs) due to its small size.
All data is with the chip in a 50 Ohm test fixture
connected via 0.025mm (1 mil) diameter wire
bonds of minimal length 0.31mm (12 mils).
