Electrical AC Characteristics

Tamb = 25 °C, unless otherwise specified

Amplifier 1

VDS = VRG1 = 5 V, VG2S = 4 V, RG1 = 100 kΩ, ID = IDSO, f = 1 MHz, Tamb = 25 °C, unless otherwise specified

Following data are valid for operating amplifier 1 (pin 1, 3, 5, 2) which is optimized for UHF applications

Remark on improving intermodulation behavior:

By setting RG1 smaller than 100 kΩ, typical value of IDSO will raise and improved intermodulation behavior will be performed.
