1) Measurement conditions are as follows: T = 25°C, V
CC
= 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.
Pin Number Function
3 RF In
8 RF Out
10 +Vcc
Others Ground
Features
· 37.5 dB Gain at 925 MHz
· 19 dBm P1dB
· 35 dBm Output IP3
· 1.1 dB Noise Figure
· Operating at Single 5 V Supply
· 80 mA Current Consumption
Specifications
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.

ALN-series is the compactly designed sur-
face-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 communica-
tion terminals and so on. It has an exceptional performance
of low noise figure, high gain, high OIP3, and low bias cur-
rent. 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 environ-
ment. The surface-mount module package including the
completed matching circuit and other components neces-
sary just in case allows very simple and convenient imple-
mentation onto the system board in mass production level.
