Guerrilla RF introduced two InGaP HBT amplifiers to the company’s family of low current LNAs and linear drivers. According to the company, both are tunable over 100 to 3800 MHz, and each exhibits "outstanding" gain and noise figure operating at a typical bias of 3.3 V and 15 mA.

In an evaluation board, the GRF2373 LNA has 1.2 dB noise figure, 18.5 dB gain and 12.5 dBm output power at 1 dB compression, operating at 1.9 GHz.

The GRF2374 LNA/driver has 1.3 dB noise figure, 16.5 dB gain and 10 dBm output at 1 dB compression, measured at 1.9 GHz in an evaluation board.

These two amplifiers, with and without integrated bypass, cover a wide bandwidth using few external components, yielding a compact, low-cost solution. The devices are assembled in a small 1.5 mm x 1.5 mm (DFN-6) footprint, making them well-suited for small cell, cellular booster and repeater transmit/receive applications in the 700 to 3800 MHz frequency bands.

Alan Ake, vice president of applications and technical marketing at Guerrilla RF, said, “The GRF2373 and GRF2374 are our initial product offerings utilizing InGaP HBT. With flexible biasing (Vdd = 2.7 to 5.0 V; Iddq = 10 to 25 mA), these amplifiers provide consistent performance at low currents and very competitive prices. We’re very excited about the introduction of our InGaP HBT portfolio. Stay tuned in the coming months for additional announcements regarding our new power amplifier products.”

Pricing and Availability

Samples and evaluation boards are available for both devices, with production quantities available in Q4 2019. Unit pricing (10,000 quantity) is $0.40 and $0.42, respectively, for the GRF2373 and GR2374.

Responding to Market Demand

According to Research and Markets, the overall wireless network infrastructure market will grow at a compound annual growth rate of over 5 percent, reaching more than $104 billion in annual spending by the end of 2020.
