A broadband energy amplifier, the GRF5112 from Guerrilla RF, offers enhanced compression efficiency over massive fractional bandwidths of as much as 40%. The system’s broad single-tuned responses allow multicarrier base stations to concurrently transmit throughout two or extra mobile bands utilizing a single RF lineup.
The GRF5112 GaAs pHEMT amplifier might be tuned over choose bands inside a frequency vary of 30 MHz to 2700 MHz. At a frequency of 1.8 GHz, the amplifier offers a achieve of 17.1 dB, OP1dB compression of 32.2 dBm, OIP3 linearity of 40 dBm, and a low noise determine of 1.7 dB when measured on the system’s customary analysis board. De-embedded noise determine values are roughly 0.2 dB decrease.
“Constructing upon the GRF5115 core, this newest iteration streamlines tuning whereas guaranteeing constant efficiency throughout course of and temperature variations. Our design staff has additionally built-in further tuning handles inside the core to optimize linearity for particular bands and bias circumstances,” stated Jim Ahne, vice chairman of selling at Guerrilla RF.
Like different GRF amplifier cores, the GRF5112 includes a versatile biasing structure that permits customizable tradeoffs between linearity and energy consumption. Provide voltages can fluctuate between 1.8 V and 5.25 V.
Costs for the GRF5112 in a 3×3-mm QFN-16 package deal begin at $1.47 in a lot of 10,000 items. Samples and analysis boards at the moment are out there.
