FMA246_1 Datasheet, PDF (1/5 Pages) Filtronic Compound Semiconductors – HIGH GAIN X-BAND MMIC AMPLIFIER

HIGH GAIN X-BAND MMIC AMPLIFIER
FMA246
Preliminary Datasheet v3.0
FEATURES:
• 8.0 – 14.0 GHz Operating Bandwidth
• 2.5 dB Noise Figure
• 30 dB Small-Signal Gain
• 19 dm Output Power
• +6V Single Bias Supply
• Adjustable Operating Current
• DC De-coupled Input and Output Ports
GENERAL DESCRIPTION:
The FMA246 is a 3-stage, reactively matched
pHEMT high-gain MMIC amplifier designed for
use over the 8 to 14 GHz bandwidth. The
supply voltage can be varied from +3V to +6V
if needed. Operating current can be adjusted
using the source resistor ladders located along
the bottom edge, by bonding a particular pad
to ground. The amplifier is unconditionally
stable over all load states (-45 to +85°C), and
conditionally stable if the input port is open-
circuited.

TYPICAL APPLICATIONS:

Note: 1. T_Ambient = 22°C; Continuous operation at IDSS is not recommended
2. 60%IDSS is achieved by bonding pads "D", "G", and "K" (shown on page 2) to ground to drive the 1st,
2nd and 3rd stage amplifiers at 50%IDSS, 50%IDSS, and 75%IDSS respectively.
