The HMC413QS16G is a high efficiency GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC Power amplifier which operates between 1.6 and 2.2 GHz. The amplifier is packaged in a low cost, surface mount 16 leaded package with an exposed base for improved RF and thermal performance. With a minimum of external components, the amplifier provides 23 dB of gain, +29.5 dBm of saturated power at 42% PAE from a +5.0V supply voltage. The amplifier can also operate with a 3.6V supply. Vpd can be used for full power down or RF output power/current control.
