Description
The SKY67175-306LF is a two-stage, GaAs pHEMT low-noise
amplifier (LNA) with active bias and high linearity performance.
The pHEMT front end of the device provides an ultra-low noise
figure (NF) while the cascode output stage provides high gain,
linearity, and efficiency.
With excellent thermal performance, the SKY67175-306LF is
rated for operation up to +105 °C.
The SKY67175-306LF is provided in a 4 x 4 mm, 16-pin Quad Flat
No-Lead (QFN) 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.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
