v03.0713
GaAs pHEMT MMIC POWER AMPLIFIER, 17 - 24 GHz Typical Applications Features
The HMC498 is ideal for: Output IP3: +34 dBm IP • Point-to-Point Radios Saturated Power: +27 dBm @ 25% PAE H • Point-to-Multi-Point Radios Gain: 24 dB • VSAT Supply Voltage: +5V • Military & Space 50 Ohm Matched Input/Output S - C R Die Size: 2.38 x 1.46 x 0.1 mm IE LIF
Functional Diagram General Description
P The HMC498 is a high dynamic range GaAs pHEMT M MMIC Power Amplifier which operates between 17 and 24 GHz. The HMC498 provides 24 dB of gain, R A +27 dBm of saturated power and 25% PAE from E a +5V supply voltage. The HMC498 amplifier can W easily be integrated into Multi-Chip-Modules (MCMs) O 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). R & P A E IN L
