Description
This group of GaAs control FETs can be used in both
series and shunt configurations. They incorporate on-chip
circuitry that eliminates the need for extra bias
components and minimizes power drain to typically 25 W.
These features make the device ideal replacements for
PIN diodes, where low DC drain is critical.
Isolation performance degrades at higher frequencies due
to package parasitics. They can be tuned out in narrow
band applications as shown in the circuit examples on the
following pages.

Operating Characteristics at 25°C (0, -5 V)
1. All measurements made in a 50
system, unless otherwise specified.
2. DC = 300 kHz.
3. RON - resistance in in low impedance state when “0” V is applied to Gate (G).
4. Insertion loss changes by 0.003 dB/°C.
5. Insertion loss and isolation typical values.
6. COFF - capacitance (pF) in high impedance state when -5 V is applied to Gate (G).
