General Description
The HMC498 is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• VSAT
• Military & Space
Output IP3: +34 dBm
Saturated Power: +27 dBm @ 25% PAE
Gain: 24 dB
Supply Voltage: +5V
50 Ohm Matched Input/Output
Die Size: 2.38 x 1.46 x 0.1 mm
The HMC498 is a high dynamic range GaAs pHEMT
MMIC Power Amplier which operates between
17 and 24 GHz. The HMC498 provides 24 dB of gain,
+27 dBm of saturated power and 25% PAE from
a +5V supply voltage. The HMC498 amplier 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 xture connected via 0.025mm (1 mil)
diameter wire bonds of minimal length 0.31mm (12
mils).
