GRF Releases New Broadband Pre-Driver for Wireless Infrastructure
Guerrilla RF (OTCQX: GUER) has released the GRF5112, a new broadband power amplifier designed for wireless infrastructure. This GaAs pHEMT amplifier offers exceptional linearity and compression over large fractional bandwidths, making it ideal for multi-carrier 5G and 4G transmitters.
Key features of the GRF5112 include:
- Operational frequency range: 30 to 2700 MHz
- Fractional bandwidth: up to 40%
- Gain: 17.1 dB at 1.8 GHz
- OP1dB compression: 32.2 dBm
- OIP3 linearity: 40 dBm
- Noise figure: 1.7 dB (1.5 dB de-embedded)
The amplifier is packaged in a 3 x 3 mm QFN-16 package and is priced starting at $1.47 for 10,000+ units.
- Release of new GRF5112 broadband power amplifier for wireless infrastructure
- Excellent linearity and compression over large fractional bandwidths (up to 40%)
- Enables multi-carrier 5G & 4G transmitters
- Flexible biasing architecture for customizable performance
- Compact 3 x 3 mm QFN-16 package
- None.
Latest GaAs pHEMT Amplifier Provides Outstanding Linearity and Compression Over Large Fractional Bandwidths, Enabling Multi-Carrier 5G & 4G Transmitters
Guerrilla RF, Inc. announces the formal release of its new GRF5112, a highly linear, broadband power amplifier that excels in delivering excellent compression performance over large fractional bandwidths of up to 40 percent. The GRF5112’s broad, single-tuned responses are ideal for cellular base station designs that integrate multiple bands into single transmit lineups. (Graphic: Business Wire)
“The GRF5112 is another example of Guerrilla RF constantly working to improve its driver amplifier offering,” says Jim Ahne, vice president of marketing at Guerrilla RF. “Building upon the GRF5115 core, this latest iteration streamlines tuning while ensuring consistent performance across process and temperature variations. Our design team has also integrated additional tuning handles within the core to optimize linearity for specific bands and bias conditions.”
The GRF5112 can be tuned to operate over select bands within the 30 to 2700 MHz frequency range. When operated at 1.8 GHz, the device delivers 17.1 dB of gain, 32.2 dBm of OP1dB compression, 40 dBm of OIP3 linearity, and a low noise figure of 1.7 dB (as measured on the device’s standard evaluation board; de-embedded NF values are approximately 0.2dB lower). Like other GRF amplifier cores, the GRF5112 features a flexible biasing architecture allowing customizable trade-offs between linearity and power consumption. Supply voltages can vary between 1.8 and 5.25 V, although most customers will elect to use a standard 5V supply with 212 mA of biasing current.
Packaged in a compact 3 x 3 mm QFN-16 package, the GRF5112 shares a pinout and matching layout with many of the company’s linear drivers and power amplifier cores.
