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.

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.
