Hittite has launched two new wideband LNA (low-noise amplifier) products which are targeted at microwave radios, VSAT, Satcom and test instrumentation applications.
The HMC1049LP5E is a GaAs MMIC pHEMT LNA which operates between 300 MHz and 20 GHz and employs a novel topology which maintains a low noise figure of 1,8 dB at low frequencies. It also delivers 15 dB of small signal gain and output IP3 of +29 dBm, while requiring only 70 mA from a +7 V supply.
P1dB output power of +14,5 dBm enables the LNA to function as an effective LO driver for balanced, I/Q or image reject mixers. Supplied in a leadless QFM 5 x 5 mm surface-mount package, the HMC1049LP5E features I/Os that are internally matched to 50 Ω.
The HMC1049 is the die version of the HMC1049LP5E. It also operates between 300 MHz and 20 GHz and provides 16 dB of small signal gain, 1,7 dB noise figure, and output IP3 of 27 dBm. The HMC1049 features P1dB output power of 16 dBm.
Internally matched to 50 Ω, the compact size and simplified biasing of the HMC1049 make it ideal for wideband multi-chip-module and subsystem applications.
