Technical Description
The SKY65094-360LF is a single stage, low-noise PA that
operates with a single 5 V power supply connected through an RF
choke (inductor L1) to the output signal (pin 7). The bias current is
set by the on-chip active bias composed of current mirror and
reference voltage transistors, which allow excellent gain tracking
over temperature and voltage variations. The device is externally
RF matched using surface-mount components to facilitate
operation over a frequency range of 824 to 849 MHz.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY65094-360LF are
provided in Table 2. The recommended operating conditions are
specified in Table 3 and electrical specifications are provided in
Table 4 (general specifications), Table 5 (698 to 716 MHz),
Table 6 (777 to 798 MHz), Table 7 (824 to 849 MHz), and Table 8
(880 to 915 MHz).
Typical performance characteristics of the SKY65094-360LF for
the 824 to 849 MHz frequency range are illustrated in Figures 3
through 10.

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 values. Exceeding any of the limits listed here may result in permanent damage to the device.
ESD HANDLING:
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 when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.
