Abstract :
In this paper, we present a power amplifier module package using a selectively anodized aluminum substrate for mobile handsets operating in the 1850 MHz to 1910 MHz PCS band. High-Q passive components (inductors, capacitors, transmission lines) for implementing the power amplifier are integrated on a 60 mum thick anodized aluminum layer and a bare InGaP HBT MMIC die is mounted on aluminum with the ability of effective heat dissipation. The fabricated module has a compact 3mm times 3mm size and exhibits 28.4 dB power gain, 41.5 % power added efficiency (PAE) and -36 dBc adjacent channel power ratio (ACPR) under a supply voltage of 3.7 V
