SKY13335-381LF: 0.1-6.0 GHz GaAs SPDT Switch
Applications
WLAN 802.11 a/b/g networks
WLAN repeaters
ISM band radios
Low power transmit receive systems
Description
The SKY13335-381LF is a pHEMT GaAs FET I/C switch. The
device features low insertion loss and positive voltage operation
with very low DC power consumption. The switch is manufactured
in a compact, low-cost 1.5 x 2.0 mm, 6-pin Micro Leadframe
Package Dual (MLPD) package.
The switch may be used in transmit/receive applications by
connecting the RF common port (RFC, pin 5) to either the OUT1 or
OUT2 port (pins 1 or 3, respectively) using a low-loss path (i.e., a
positive voltage applied to either the VCTL1 or VCTL2 pins). The
switch is a reflective short on the isolated port.
The 6-pin MLPD package and pinout are shown in Figure 1. A
functional block diagram is shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1. The absolute maximum ratings of the SKY13335-381LF
are provided in Table 2 and recommended operating conditions
listed in Table 3. Electrical specifications are provided in Table 4.
Typical performance characteristics for the SKY13335-381LF are
shown in Figures 3, 4, and 5.
The state of the SKY13335-381LF is determined by the logic
provided in Table 5.
