HMC608LC4 v02.1208 Typical Applications Features The HMC608LC4 is ideal for: Output IP3: +33 dBm • Point-to-Point Radios Saturated Power: +27.5 dBm @ 23% PAE • Point-to-Multi-Point Radios Gain: 29.5 dB • Military End-Use Supply: +5V @ 310 mA 9 Amplifiers - Linear & Power - SMT GaAs pHEMT MEDIUM POWER AMPLIFIER, 9.5 - 11.5 GHz 50 Ohm Matched Input/Output RoHS Compliant 4x4 mm SMT Package Functional Diagram General Description The HMC608LC4 is a high dynamic range GaAs pHEMT MMIC Medium Power Amplifier housed in a leadless “Pb free” SMT package. The amplifier has two modes of operation: high gain mode (Vpd pin shorted to ground); and low gain mode (Vpd pin left open). The electrical specifications in the table below are shown for the amplifier operating in high gain mode. Operating from 9.5 to 11.5 GHz, the amplifier provides 29.5 dB of gain, +27.5 dBm of saturated power and 23% PAE from a +5V supply voltage. Noise figure is 6 dB while output IP3 is +33 dBm. The RF I/Os are DC blocked and matched to 50 Ohms for ease of use. The HMC608LC4 eliminates the need for wire bonding, allowing use of surface mount manufacturing techniques.
