Analog Devices Inc (ADI) of Norwood, MA, USA (which provides ICs for analog and digital signal processing applications) has launched a medium-power distributed driver amplifier that operates at 24-35GHz, suitable for civil and defense communications systems, including point-to-point and point-to-multi-point radios and VSAT and SatCom applications.
Based on a gallium arsenide (GaAs) pseudomorphic high-electron mobility transistor (pHEMT) design and operating from a DC supply of +5V at 225mA, the HMC1131 provides 22dB of gain, +35dBm output IP3, and +24dBm of output power at 1dB gain compression (P1dB). The amplifier is capable of supplying +25dBm of saturated output power with 16% power-added efficiency (PAE).
Housed in a compact, leadless 4mm x 4mm ceramic surface-mount package, the HMC1131 reduces the number of components required to achieve the desired output power and small-signal gain, lowering development costs and design time by enabling simpler transmit line-ups and higher integration.
Pricing of the HMC1131 is $34.15 each in 1000-unit quantities.
