The race to WiMAX is on and it can be seen in many parts of the industry. For instance, Hittite Microwave Corp. just came out with a high-efficiency GaAs InGaP HBT MMIC power amplifier. Although the HMC409LP4 is suited for 802.16d/e WiMAX applications, the amplifier also is useful in other broadband fixed wireless applications in that frequency range. It operates between 3.3 and 3.8 GHz.
Using a minimum of external components, the amplifier provides 31 dB of gain and +32.5 dBm of saturated power from a single +5-V supply. The power control (Vpd) can be used for full power-down or RF output power/current control. The HMC409LP4 combines high gain and linearity to help WiMAX OEMs meet 802.16d/e requirements.
The amplifier is packaged in a low-cost, leadless 4-×-4-mm QFN SMT package. Samples and evaluation pc boards are available from stock and can be ordered online. For information on pricing, please contact the company.
