Description
Technical Description
The SKY66115-11 consists of a complete T/R chain with a T/R
switch contained in the module. The module has a shutdown
mode to minimize power consumption.
Transmit Path
The transmit path contains an amplifier optimized for saturated
performance. The output is internally matched for optimum
output power and efficiency into a 50
Ω
load impedance. The
output is passed through a harmonic filter before being fed
through the switch. The input provides a good return loss into a
50
source impedance.
Operation Mode Control
The operating modes are controlled by the two digital pins (CSD
and CTX, pins 15 and 16, respectively). The control logic truth
table is provided in Table 8.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY66115-11 are provided
in Table 2. Recommended operating conditions are specified in
Table 3 and electrical specifications are provided in Tables 4
through 7. Table 8 shows the mode logic truth table.
Typical performance characteristics are shown in Figures 3
through 8.

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.
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.
