Description
The SKY67012-396LF is a GaAs, pHEMT low-noise amplifier
(LNA) with an integrated active bias. The advanced GaAs pHEMT
enhancement mode process provides excellent return loss, low
noise, and high linearity.
The device offers the ability to externally adjust the supply
current. The supply voltage is applied to the RF-OUT/VDD pin
through an RF choke inductor. The VBIAS pin should be connected
to the RF_OUT/VDD pin through an external resistor to control the
supply current. Both RF_OUT/VDD and RF_IN pins should be DC
blocked to ensure proper operation.
The SKY67012-396LF is manufactured in a compact, 2 x 2 mm,
8-pin Dual Flat No-Lead (DFN) package. A functional block
diagram is shown in Figure 1. The pin configuration and package
are shown in Figure 2. Signal pin assignments and functional pin
descriptions are provided in Table 1.
