ATF-55143 Application Note 1376
... ATF-55143 uses a 2.0 Volt bias and provides a +21 dBm intercept point at 10 mA drain current. In addition, the ATF55143 is an enhancement mode device and, thus, does not require a negative gate voltage. A depletion mode PHEMT pulls maximum drain current when Vgs = 0V, whereas an enhancement mode PHE ...
