Guerrilla RF explicitly lists this product for the selected Skyworks code in its Guerrilla Replace lookup. The source covers drop-in or functional alternatives; this row is retained as a qualified engineering comparison, not a verified drop-in. Published target parameters: Description: Broadband LNA / Linear Driver; Frequency Range(GHz): 0.029-3.8; Reference Conditions: 5V/135mA/2.5GHz; Gain(dB): 12.5; NF(dB): 0.95; OP1dB (dBm): 26.7; OIP3 (dBm): 42.3; Vdd Range (V): 1.8-5.0; Idd Range (mA): 30-150; Features: High linearity; low noise; flex bias; Package (mm): 1.5 DFN-6. Values describe the Guerrilla RF target at the stated reference conditions, not guaranteed equivalence to Skyworks or performance across the whole tuning range. Consult current datasheets, custom tunes and parametric charts. Check RF band and topology, gain, noise, linearity, power/compression, bias/current, control interface, package dimensions, pinout, PCB footprint, matching networks, thermal and stability requirements. Exact published codes and any -W suffix are preserved; omitted Skyworks package or ordering suffixes are not invented. Confirm the complete ordering code before purchasing. A pre-production asterisk on the source denotes a development product; confirm production status and availability. Reverse replacement approval and shared qualification are not established.
