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 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.
