Amplifier 2
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 2 (pin 3, 4, 2, 5) 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.
