HMC498
v03.0713 LINEAR & POWER AMPLIFIERS -CHIP GaAs pHEMT MMIC
POWER AMPLIFIER, 17 -24 GHz
Typical Applications Features The HMC498 is ideal for: Output IP3: +34 dBm • Point-to-Point Radios Saturated Power: +27 dBm @ 25% PAE • Point-to-Multi-Point Radios Gain: 24 dB • VSAT Supply Voltage: +5V • Military & Space 50 Ohm Matched Input/Output
Die Size: 2.38 x 1.46 x 0.1 mm General Description Functional Diagram 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 +5V 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). Electrical Specifications, TA = +25° C, Vdd = 5V, Idd = 250mA*
