DATA SHEET • SKY66101-11: HIGH POWER RF FEM
Technical Description
The SKY66101-11 consists of a complete T/R chain with T/R
switches contained in the module. An SP3T switch selects
between receive, transmit, and transmit bypass paths. The
module has a shutdown mode to minimize power consumption.
Three digital input control pins (CSD, CPS, and CTX) are used to
select between shutdown, T/R, or transmit bypass mode,
respectively. A fourth digital control pin (ANT_SEL) is used to
select between antenna ports 1 and 2.
The bypass mode can also be configured to power-down the PA
and remove it from the RF path using an internal single-pole,
single-throw (SPST) switch.
The transmit path contains a PA optimized for saturated
performance. The PA can be passed through an external
impedance matching network and harmonic filter before being fed
through the SP3T switch. External inductors for each of the two
PA stages provide maximum application flexibility.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY66101-11 are provided
in Table 2. The recommended operating conditions are specified
in Table 3 and electrical specifications are provided in Tables 4
through 8.
The state of the SKY66101-11 is determined by the logic provided
in Table 9.

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
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.
