The HMC300LM1 is a low cost broadband surface mount medium power amplifier that operates between 25.5 and 33.5 GHz. A 0.25 um power pHEMT process is used to achieve efficient gain and output power performance. High volume surface mount re-flow assembly techniques may be used to mount the amplifier to the end user's PCB. The LM1 package eliminates the need for wire bonding or die attach mounting. The amplifier provides 15 dB of gain and +24 dBm of saturated output power across various microwave radio bands. This millimeter wave amplifier requires no external RF matching components and minimal DC bypass components. The amplifier operates from a +6V Vdd and a -0.35 Vgg gate bias.
