General Description
The XP1035-QH is a packaged linear power amplifier
that operates over the 5.9-9.5 GHz frequency band. The
device provides 26 dB gain and 39 dBm Output Third
Order Intercept Point (OIP3) across the band and is
offered in an industry standard, fully molded 4x4mm
QFN package. The packaged amplifier is comprised of
a three stage power amplifier with an integrated,
temperature compensated on-chip power detector.
The device includes on-chip ESD protection structures
and DC by-pass capacitors to ease the implementation
and volume assembly of the packaged part. The device
is manufactured in GaAs PHEMT device technology
with BCB wafer coating to enhance ruggedness and
repeatability of performance. The XP1035-QH is well
suited for Point-to-Point Radio, LMDS, SATCOM and
VSAT applications.

App Note [1] Biasing -
As shown in the Pin Designations table, the device is operated by biasing VD1,2,3 at 5.0V with 70, 140, 280mA respectively.
It is recommended to use active bias to keep the currents constant in order to maintain the best performance over temperature. Depending on the
supply voltage available and the power dissipation constraints, the bias circuit may be a single transistor or a low power operational amplifier, with
a low value resistor in series with the drain supply used to sense the current. The gate of the pHEMT is controlled to maintain correct drain current
and thus drain voltage. The typical gate voltage needed to do this is -1.0V. Make sure to sequence the applied voltage to ensure negative gate bias
is available before applying the positive drain supply.
App Note [2] Board Layout -
As shown in the board layout, it is recommended to provide 100pF decoupling caps as close to the bias pins as
possible, with additional 10µF decoupling caps.
