plerowTM ALN0892T1 Internally Matched LNA Module Features Description 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 communication 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. · S21 = 36.5 dB @ 824 MHz = 35.5 dB @ 894 MHz · S21 = 35.5 dB @ 890 MHz = 34.5 dB @ 960 MHz · NF of 0.8~0.85 dB over Frequency · Unconditionally Stable · Single 5V Supply · High OIP3 @ Low Current Specifications (in Production) 2-stage Single Type Typ. @ T = 25°C, Vs = 5 V, Freq. = 859.925 MHz, Zo.sys = 50 ohm Specifications Parameter Unit CDMA Min Frequency Range Typ GSM Max Min 894 890 Typ Max More Information MHz 824 Gain dB 35 Gain Flatness dB ± 0.5 ± 0.6 ± 0.5 ± 0.6 Noise Figure dB 0.8 0.85 0.85 0.9 Output IP3 S11 / S22 (1) dBm (2) 34 37 36 dB Output P1dB Switching Time 36 36 dBm (3) 960 35 20 -18 / -15 21 20 - Supply Current mA 100 Supply Voltage V ASB Inc., 4th Fl.

The capacitance value may be determined by customer’s DC supply status. 2) So-called DC blocking capacitors are always necessarily placed at the input and output port for allowing only the RF signal to pass and blocking the DC component in the signal. The DC blocking capacitors are included inside the LNA module. Therefore, C1 & C2 capacitors may not be necessary, but can be added just in case that the customer wants. The value of C1 & C2 is determined by considering the application frequency.
