Description
The SKY66119-11 is a high-performance, transmit/receive (T/R)
front-end module (FEM). The device provides a complete T/R
chain with T/R switches.
The device transmit chain features +30.5 dBm output. The device
receive chain features a low-noise amplifier (LNA) with a 1.3 dB
noise figure (NF) and 15.5 dB gain. The cascaded NF and gain,
taking into account the 0.4 dB insertion loss transmit/receive
antenna switch, are 1.7 dB and 15 dB, respectively.
The module also has a shut-down mode, PA bypass mode, and
LNA bypass mode to minimize power consumption.
The device is mounted in a 28-pin, 6 x 6 mm Multi-Chip Module
(MCM) surface-mount technology (SMT) package, which allows
for a highly manufacturable low-cost solution.
A block diagram of the SKY66119-11 is shown in Figure 1. The
device package and pinout for the 28-pin MCM are shown in
Figure 2. Signal pin assignments and functional pin descriptions
are provided in Table 1.

DATA SHEET • SKY66119-11: TRANSMIT/RECEIVE FRONT-END MODULE
Technical Description
The SKY66119-11 consists of a complete T/R chain with T/R
switches contained in the module. A single-pole, triple-
throw (SP3T) switch selects between the receive, transmit, and
transmit bypass paths. The module has a shut-down mode to
minimize power consumption.
Three digital input pins (TR, EN, and BYP) are used to select
between transmit, transmit bypass, receive, receive bypass, or
shutdown mode.
Transmit Path
The transmit path contains a power amplifier (PA) optimized for
saturated performance. The PA output is internally matched for
optimum output power and efficiency into a 50
Ω
load
impedance. The PA output is passed through an harmonic filter
before being fed through the SP3T switch. The PA input provides
a good return loss into a 50
Ω
source impedance.
Transmit output power is controlled by the VPC pin, which is
normally set to 2.25 V DC voltage. The nominal DC input
impedance into the VPC pin is 50 kΩ.
Receive Path
The receive path contains an LNA with bypass switch. The LNA
impedance matching networks are internal to the module and
have been optimized for a low NF while maintaining good return
losses into a 50
Ω
source and load impedance. The receive arm
of the SP3T switch and the LNA input are connected to module
pins to allow an external filter to be inserted into the receive path.
LNA biasing can be independently lowered with an external bias
resistor between the RBIAS pin and ground.
Operation Mode Control
The five SKY66119-11 operating modes are controlled by the
three digital pins: TR, EN, and BYP (pins 2, 3, and 4, respectively).
The control logic truth table is provided in Table 2.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY66119-11 are provided
in Table 3. Recommended operating conditions are specified in
Table 4. Electrical specifications are provided in Tables 5, 6,
and 7.

1 See Table 4 for logic 0 and 1 characteristics.
“X”
= don’t care state, defined as a valid state of logic 1 or 0. Control signals must be a valid logic 1 or 0.
Performance is not guaranteed if control inputs are floated.
2 In the high state, TR, EN, and BYP have an input current of 33
μA
due to an internal 100 kΩ pulldown resistance. For the lowest leakage current, the high state is not recommended for TR
and BYP when the device is in shutdown mode (EN = 0).

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 typical value as provided in Table 4.
2 Nominal thermal resistance, junction to case, is 18° C/W.
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.
