Hittite Microwave introduces a highly efficient family of Heterojunction Bipolar Transistor (HBT) MMIC Power Amplifiers, operating between 4.4 - 7.0 GHz with up to +29 dBm output power. These amplifiers are ideal for low cost UNII and HiperLAN applications from 5.0 - 6.0 GHz. The HMC415LP3 provides 20 dB of gain and +26 dBm of saturated power at 34% PAE from a +3.0 V supply over 4.4 to 6.0 GHz. The HMC406MS8G provides 18 dB of gain and +29 dBm of saturated power at 38% PAE from a +5.0 V supply over 5.0 to 6.0 GHz. The HMC407MS8G provides 15 dB of gain and +29 dBm of saturated power at 28% PAE from a +5.0 V supply over 5.0 - 7.0 GHz. In each PA a Power Down Control input (Vpd) can be used for RF output power/current control.
The HMC415LP3 and HMC406MS8G require minimum external components while the HMC407MS8G requires no external matching, yielding a true 50 ohm I/O amplifier. The HMC415LP3 is packaged in a low cost, leadless surface mount package (3.0 mm × 3.0 mm) while the HMC406MS8G and HMC407MS8G are both packaged in low cost, surface mount 8 leaded MSOP packages (3.0 mm × 5.0 mm). All three have an exposed base for improved RF and thermal performance.
