Broadband Single Control Amplifier Boasts Low Loss Bypass

Guerrilla RF Inc. introduces the GRF4142 amplifier targeted at small cells, cellular boosters and other broadband, high-performance applications offering broadband frequency coverage with a minimal number of external components.  It is offered in a 1.5 x 1.5 mm DFN-6 package, thus sharing a common pin out with numerous other Guerrilla RF devices including the GRF400X and GRF201X device families.


The GRF4142 can be operated over a range of Vdd from 1.8 to 5.0 volts and Iddq can be controlled independently from Vdd, thus allowing the device efficiency to optimized for a given application requirement.  The device can easily cover fractional bandwidths > 20 percent, with a single set of external components.  Gain Mode performance of 1900 MHz, with Gain: 16.0 dB, OP1dB: 19.0 dBm, OIP3: 34 dBm, Noise Figure: 0.95 dB at 5.0 volts and 50 mA.  Bypass Mode performance of 1900 MHz, with Gain: -1.5 dB, OP1dB: 20 dBm, OIP3: 40 dBm at 5.0 volts and < 1.0 mA.


GRF4142 samples and evaluation boards are available now.  Pricing is $0.65 each/10,000.  Production is scheduled for Q3 2017. For more information, visit
