QPA7489A
DC to 3000 MHz, CASCADABLE SiGe HBT
MMIC AMPLIFIER
The QPA7489A is a high performance SiGe HBT MMIC
amplifier. A Darlington configuration provides high FT and
excellent thermal performance. The heterojunction increases
breakdown voltage and minimizes leakage current between
junctions. Cancellation of emitter junction non-linearities results
in higher suppression of intermodulation products. Only two DC-
blocking capacitors, a bias resistor, and an optional RF choke
are required for operation.

Exceeding any one or a combination of the Absolute Maximum Rating
conditions may cause permanent damage to the device. Extended
application of Absolute Maximum Rating conditions to the device may
reduce device reliability. Specified typical performance or functional -
operation of the device under Absolute Maximum Rating conditions is
not implied.

Notes:
1. Load Condition 1: ZL = 50ꢀΩ
2. Load Condition 2: ZL = 10:1 VSWR, Take into account out of band load VSWR
presented by devices such as SAW filters to determine maximum RF input
power. Reflected harmonic levels in saturation are significant.
3. Operation of this device beyond any one of these limits may cause permanent
damage. For reliable continuous operation, the device voltage and current
must not exceed the maximum operating values specified in the table on this
page.
4. Bias Conditions should also satisfy the following expression: IDVD <(TJ -TL)/
RTH, and TL =TLEAD
.
