Remark on improving intermodulation behavior:
By setting RG1 smaller than 100 kΩ, e.g. 68 kΩ typical value of IDSO will raise and improved intermodulation behavior will be performed.
Amplifier 2
VDS = VRG1 = 5 V, VG2S = 4 V, RG1 = 56 kΩ, ID = IDSO, f = 1 MHz, Tamb = 25 °C, unless otherwise specified
Following data are valid for operating amplifier 2 (pin 6, 4, 2, 5) which is optimized for VHF applications
Remark on improving intermodulation behavior:
By setting RG1 smaller than 56 kΩ, typical value of IDSO will raise and improved intermodulation behavior will be performed.
