300 To 2200 MHz Ultra Low-Noise Amplifier: SKY67150-396LFSource: Skyworks Solutions, Inc.
The SKY67150-396LF is GaAs, pHEMT Low-Noise Amplifier (LNA) with an active bias, high linearity, superior gain, and industryleading Noise Figure (NF) performance. The device features Skyworks advanced, pHEMT enhancement mode process in a compact 2 x 2 mm, 8-pin Dual Flat No-Lead (DFN) package.
The internal active bias circuitry provides stable performance over temperature and process variation. The device offers the ability to externally adjust supply current. Supply voltage is applied to the RFOUT/VDD pin through an RF choke inductor. The RFIN and RFOUT/VDD pins should be DC blocked to ensure proper operation.
The SKY67150-396LF operates in the frequency range of 300 to 2200 MHz using a common layout and band-specific tunes. Operation with high gain and a low NF at frequencies as low as 100 MHz is possible with degraded input return loss.
