Description
The plerow^TM ALN-series is the compactly designed surface-mount
module for the use of the LNA with or without the following gain blocks in
the infrastructure equipment of the mobile wireless (CDMA, GSM, PCS,
PHS, WCDMA, DMB, WLAN, WiBro, WiMAX), GPS, satellite
communication terminals and so on. It has an exceptional performance
of low noise figure, high gain, high OIP3, and low bias current. The
stability factor is always kept less than unity over the application band in
order to confirm its unconditionally stable implementation to the
application system environment. The surface-mount module package
including the completed matching circuit and other components
necessary just in case allows very simple and convenient
implementation onto the system board in mass production level.

1) Operating temperature is -40°C to +85°C.
2) OIP3 is measured with two tones at an output power of 3 dBm / tone separated by 1 MHz.
3) Note: We recommend that the VSWR toward a source and load be less than 1:4 to avoid an unwanted oscillation.

Ground
Note: 1. The number and size of ground via holes in
a circuit board is critical for thermal RF
grounding considerations.
2. We recommend that the ground via holes be
placed on the bottom of all ground pins for
better RF and thermal performance, as
shown in the drawing at the left side.
