Standby
Standby mode is achieved by disconnecting BIAS as
shown in Figure 1. Avoid capacitance at the BIAS pin
by connecting the bias resistor from BIAS to the switch.
Layout Issues
A properly designed PC board is essential to any
RF/microwave circuit. Use controlled impedance lines
on all high-frequency inputs and outputs. Bypass with
decoupling capacitors located close to the device V
CC
pin. For long V
CC
lines, it may be necessary to add
additional decoupling capacitors. These additional
capacitors can be located farther away from the device
package. Proper grounding of the GND pins is essen-
tial. If the PC board uses a topside RF ground, connect
it directly to all GND pins. For a board where the
ground plane is not on the component layer, the best
technique is to connect the GND pins to the board with
a plated through-hole located close to the package.
