MGA-565P8
20 dBm P_sat High Isolation Buffer Amplifier
Data Sheet
Description
The MGA-565P8 is designed for use in LO chains to drive
high dynamic range passive mixers. It provides high
isolation, high gain, and consistent output power. It is
a GaAs MMIC, fabricated using Avago Technologies’ cost
effective, reliable enhancement mode PHEMT (Pseu-
domorphic High Electron Mobility Transistor)^[1] process.
This device is housed in the LPCC 2x2 mm package. This
package offers good thermal dissipation and RF charac-
teristics.
MGA-565P8 features a saturated power of 20 dBm (with
0 dBm input power) and reverse isolation in excess of
40 dB at 2 GHz. The saturated output power can be set
between 9 dBm and 20 dBm using an external resistor,
with a corresponding adjustment in current consump-
tion.
Notes:
1. Enhancement mode technology employs a single positive V_gs,
eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
2. Conform to JEDEC reference outline MO229 for DRP-N
