Guerrilla RF samples GRF2113 high-linearity broadband gain block
Guerrilla RF Inc (GRF) of Greensboro, NC, USA — which develops and manufactures radio-frequency integrated circuits (RFICs) and monolithic microwave integrated circuits (MMICs) for wireless applications — is sampling the GRF2113, a next-generation variant of its GRF2013 gallium arsenide (GaAs) pseudomorphic high-electron-mobility transistor (pHEMT) amplifier core. The gain of this new variant surpasses that of its predecessor by up to 3.5dB, providing extra headroom in wireless infrastructure receive and transmit setups where marginal cascaded gain is a concern.
“The GRF2013 has proven to be one of the company’s most successful products to date, having sold well over 15 million units in the past five years,” says Jim Ahne, VP of marketing. “With the gain enhancements achieved with the GRF2113, Guerrilla RF is well positioned to maintain its lead in the gain block market,” he believes. “This part is expected to be highly popular among our 5G, point-to-point and cellular repeater/booster customers, who seek additional gain options for their radio lineups. The GRF2113 complements the previously released GRF2013, GRF2010, and GRF2010 series, offering designers a choice between nominal gain levels of 21.5dB, 18dB, 15dB and 10dB.”
The GRF2113 is designed to operate at 50–4000MHz while using a single, broadband tune. When used at 2.5GHz, it delivers 21.5dB of gain, 22dBm of OP1dB compression, 38dBm of OIP3 linearity, and a low noise figure of 1.75dB (as measured on the device’s standard evaluation board; de-embedded NF values are about 0.2dB lower).
As with most of GRF’s amplifier cores, the GRF2113 has a flexible biasing architecture, allowing for customizable tradeoffs in linearity and power consumption. Supply voltages can vary between 3V and 6V, although most customers will elect to use a standard 5V supply with 115mA of biasing current.
The GRF2113 utilizes Guerilla RF’s 2mm x 2mm DFN-8 package, following an industry standard in both pinout and footprint.
Samples and evaluation boards are available for the GRF2113. Prices start at $0.98 (10,000-up, EXW USA).
