The GRF5521 provides ¼ watt of power from 2.11 GHz to 2.17 GHz,
Cellular-connected devices need amplifiers to boost their transmitted signals enough to reach a tower. To that end, Guerilla RF has added the GRF5521 to its line of power amplifiers.
The GRF5521 produces RF signal with up to 1/4 W of power. It operates in the n1, n65, and n66 5G new radio (NR) bands. The PA delivers 23.5 dBm of linear power over a temperature range of -40°C to 85°C while maintaining ACLR levels of better than -45 dBc, IMD3 levels less than -22 dBm, EVM levels less than 1%, and PAE Efficiencies greater than 20%. It accomplishes these parameters without the aid of supplemental linearization schemes such as digital pre-distortion (DPD). The gain-frequency plot shows the device’s linearity over its operating frequency range.
Applications include residential and commercial repeaters/boosters, femtocells, picocells, and cable loss compensators found in automotive “shark fin” antennas.
