Driver Amplifiers

Mon, 05/06/2002 - 7:16am
Hittite Microwave introduces a pair of Heterojunction-Bipolar-Transistor (HBT) Medium Power MMIC Amplifiers, operating between 1.7 - 2.8 GHz with up to +27 dBm output power and +40 dBm OIP3 from a single supply voltage. The HMC413QS16G is ideal for use as a linear PA driver in cellular, PCS or 3G base-station and repeater transmitters. Data intensive driver applications such as W-CDMA, 802.11b WLAN & MMDS will find the HMC414MS8G an excellent choice.

The HMC413QS16G provides 22 dB of gain and +29.5 dBm of saturated power at 42% PAE from a +5.0 V supply over 1.7 to 2.3 GHz. The HMC414MS8G provides 20 dB of gain and +30 dBm of saturated power at 32% PAE from a +5.0 V supply over 2.2 to 2.8 GHz. In both cases, the HMC414MS8G and the HMC413QS16G can operate using a 3.6 V supply. Each product has a power down control input (Vpd) that can be used for efficient control of DC current consumption and RF output power.
