Description
The SKY13344-378LF is a pHEMT GaAs FET I/C switch. The
switch may be used in transmit/receive applications by
connecting the RF common port (INPUT, pin 5) to either the
OUTPUT1 or OUTPUT2 port (pin 1 or 3, respectively) using a low
loss path (i.e., a positive voltage applied to either VCTL1 or VCTL2
pins). The switch is “reflective short” on the isolated port.
The switch is manufactured in a compact, 1 x 1 mm, 6-pin
exposed pad plastic Micro Leadframe Package Dual (MLPD)
package.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.
