Description
The SKY67151-396LF is GaAs, pHEMT low-noise amplifier (LNA)
with an active bias, high linearity, superior gain, and industryleading noise figure (NF) performance from 700 to 3800 MHz. 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 SKY67151-396LF operates in the frequency range of 0.7 to
3.8 GHz using a common layout and band-specific tunes.
