NOTE: Typical power and efficiency is shown above. The devices were biased nominally at V
DS
= 5V, I
DS
= 50%
of I
DSS
, at a test frequency of 1.85 GHz. The test devices were tuned (input and output tuning) for maximum
output power at 1dB gain compression.

Note:
pHEMT
devices have
enhanced
intermodulation performance. This yields OIP3
values of about P
1dB
+ 14dBm. This IMD
enhancement is affected by the quiescent bias and
the matching applied to the device
.

Note: The recommended method for measuring I
DSS
, or
any particular I
DS
, is to set the Drain-Source voltage (V
DS
)
at 1.3V. This measurement point avoids the onset of
spurious self-oscillation which would normally distort the
current measurement (this effect has been filtered from
the I-V curves presented above). Setting the V
DS
> 1.3V
will generally cause errors in the current measurements,
even in stabilized circuits.
