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 communi-
cation 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 sys-
tem 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 4:1 to avoid an unwanted oscillation.
4) S11/S22 (max) is the worst value within the frequency band.

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.
