GENERAL DESCRIPTION:
TYPICAL APPLICATIONS:
The FPD750DFN is a packaged depletion
mode AlGaAs/InGaAs pseudomorphic High
Electron Mobility Transistor (pHEMT). It
utilizes a 0.25 µm x 750 µm Schottky barrier
Gate, defined by high-resolution stepperbased photolithography. The recessed and
offset Gate structure minimizes parasitics to
optimize performance, with an epitaxial
structure designed for improved linearity over
a range of bias conditions and input power
levels.

of wireless infrastructure systems.

Total Power Dissipation defined as: PTOT ≡ (PDC + PIN) – POUT,
where PDC: DC Bias Power, PIN: RF Input Power, POUT: RF Output Power
Total Power Dissipation to be de-rated as follows above 22°C:
PTOT= 1.5 - (0.011W/°C) x TPACK
where TPACK= source tab lead temperature above 22°C
(coefficient of de-rating formula is the Thermal Conductivity)
Example: For a 65°C carrier temperature: PTOT = 1.5W – (0.011 x (65 – 22)) = 1.03W
5
The use of a filled via-hole directly beneath the exposed heatsink tab on the bottom of the package is strongly
recommended to provide for adequate thermal management. Ideally the bottom of the circuit board is affixed to a
heatsink or thermal radiator
BIASING GUIDELINES:
•
•
•
Active bias circuits provide good performance stabilisation over variations of operating
temperature, but require a larger number of components compared to self-bias or dual-biased.
Such circuits should include provisions to ensure that Gate bias is applied before Drain bias,
otherwise the pHEMT may be induced to self-oscillate
Dual-bias circuits are relatively simple to implement, but will require a regulated negative voltage
supply for depletion-mode devices.
For standard Class A operation, a 50% of IDSS bias point is recommended. A small amount of
RF gain expansion prior to the onset of compression is normal for this operating point. Note that
pHEMTs, since they are “quasi- E/D mode” devices, exhibit Class AB traits when operated at 50%
of IDSS. To achieve a larger separation between P1dB and IP3, an operating point in the 25% to
33% of IDSS range is suggested. Such Class AB operation will not degrade the IP3 performance.

Drain-Source Voltage (V)
Note: The recommended method for measuring IDSS, or any particular IDS, is to set the Drain-Source voltage (VDS)
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 VDS > 1.3V
will generally cause errors in the current measurements, even in stabilised circuits.
Recommendation: Traditionally a device’s IDSS rating (IDS at VGS = 0V) was used as a predictor of RF power, and
for MESFETs there is a correlation between IDSS and P1dB (power at 1dB gain compression). For pHEMTs it can
be shown that there is no meaningful statistical correlation between IDSS and P1dB; specifically a linear regression
analysis shows r2 < 0.7, and the regression fails the F-statistic test. IDSS is sometimes useful as a guide to circuit
tuning, since the S22 does vary with the quiescent operating point IDS.
