The SKY67226-11 LNA is comprised of a single stage high linearity, high gain low
noise GaAs pHEMT amplifier integrated with all required matching components,
greatly reducing PCB area and offering low thermal resistance for enhanced mean
time between failure (MTBF). The module is completely DC bypassed and is
realized in a 4x4 mm2 16-pin Skyworks Green Multi-Chip Module package. The LNAs
internal active bias circuitry provides stable performance over wide temperature
range. The advanced GaAs pHEMT enhancement mode process also provides excellent
mid band return loss (16 dB), high gain (16.5 db), very high linearity (>37
dBm OIP3) coupled with low noise figure (1.0 db).
The module's only
external component is utilized to adjust the supply current over a range of 30
to 100 mA and the device can also be operated over a 3.3 to 5V input voltage
range. The SKY67226-11 is specified over a frequency range of 2.2 to 3.0 GHz and
a standard evaluation board centered at 2.5 GHz is available. For lower
frequency operation (0.4 – 0.7 GHz) the pin-compatible SKY67215-11 should be
used, for (0.5 – 1.2 GHz) the pin compatible SKY67216-11 is the recommended
solution, and for (1.6 – 2.1 GHz) the pin compatible SKY67221-11 should be
utilized. Samples are available upon request. Applications include LTE Pico
Cells and Signal Boosters, In Building Wireless Systems, Wireless Sensors,
Satellite, and ISM Band transceivers
