PlerowTM ALN0925 Low Noise Amplifier Features Description · 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 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. 2-stage Single Type Specifications Parameter Unit Specification MHz 890 ~ 960 Gain dB 37.5 Gain Flatness dB ± 0.5 Noise Figure dB 1.1 Frequency Range Output IP3 dBm 35 S11 / S22 dB -14 / -14 Output P1dB dBm 19 Supply Current mA 80 Supply Voltage V 5 Impedance Max.

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.
