1 / 4 page 1/4 www.asb.co.kr February 2011 plerowTM ALN1922 Internally Matched LNA Module The plerowTM 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, CATV 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 more than unity over the application band in order to ensure 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. Parameter Unit Specifications Min Typ Max Frequency Range MHz 1850 1995 Gain dB 29.0 30.0 Gain Flatness dB 0.4 0.5 Noise Figure dB 0.65 0.7 Output IP3 dBm 37.5 39 S11/S22 dB -18/-9 Output P1dB dBm 20 21 Switching Time (3) sec - Supply Current mA 170 200 Supply Voltage V 5 Impedance 50 Max. RF Input Power dBm C.W 29~31 (before fail) Package Type & Size mm Surface Mount Type, 13Wx13Lx3.8H Operating temperature is -40 C to +85C. 1) OIP3 is measured with two tones at an output power of 4 dBm/tone separated by 1 MHz. 2) S11/S22 (max) is the worst value within the frequency band. 3) Switching time means the time that takes for output power to get stabilized to its final level after switching DC voltage from 0 V to VS. Pin Number Function 3 RF In 8 RF Out 10 Vs Others Ground Outline Drawing (Unit: mm) Features · S21 = 30.4 dB@1850 MHz = 29.6 dB@1995 MHz · NF of 0.65 dB over Frequency · Unconditionally Stable · Single 5 V Supply · High OIP3@Low Current 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. Description ALN1922 ASB Inc.
