TM
The plerow 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 wirelss (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) Measurement conditions are as follows: T = 25°C, VCC = 5 V, Freq. = 925 MHz, 50 ohm system.
2) OIP3 is measured with two tones at an output power of 10 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.

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.
