| PlerowTM ALN0925 Low Noise Amplifier 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 Description 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.

Venture Town Bldg., 367-17 Goijeong-Dong, Seo-Gu, Daejon 302-716, Korea 1) Measurement conditions are as follows: T = 25C, 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. Outline Drawing ALN plerow Pin Number 3 8 Function RF In RF Out +Vcc Ground ASB Inc. TOP BOTTOM 10 Others SIDE : Soldering area 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. :0.4 plated thru holes to ground plane (Unit: mm) 1/4 SUGGESTED FOOTPRINT www.asb.co.kr August 2005 PlerowTM ALN0925 Low Noise Amplifier S-parameters Stability Factor (K) Noise Figure & Gain Flatness OIP3 2/4 www.asb.co.kr August 2005 PlerowTM ALN0925 Low Noise Amplifier P1dB 3/4 www.asb.co.kr August 2005 PlerowTM ALN0925 Low Noise Amplifier Recommended Soldering Reflow Process 4/4 www.asb.co.kr August 2005 |
