Distributed power amp supplies +25dBm saturated output power
Analog Devices has introduced a medium-power, distributed driver amplifier which operates between 24 and 35GHz. The HMC1131 provides 22dB of gain, +35dBm output IP3, and +24dBm of output power at 1dB gain compression. The amplifier reduces the number of components required to achieve the desired output power and small signal gain, which lowers development costs and design time by enabling simpler transmit line-ups and higher integration.
Based on a GaAs pHEMT (pseudomorphic High-Electron Mobility Transistor) design, the HMC1131 is suitable for civil and defence communications systems, including point-to-point and point-to-multi-point radios and VSAT and SATCOM applications. The HMC1131 is capable of supplying +25dBm of saturated output power with 16% PAE and operates from a DC Supply of +5V at 225mA.
Housed in a compact, leadless 4x4 mm ceramic surface-mount package, the HMC1131 is available now in sample and production quantities, at a price of $34.15 per unit, in 1,000 unit quantities.
