plerowTM ALN4500
Internally Matched LNA Module Features
S21 = 18.4 dB @ 4000 MHz = 17.6 dB @ 5000 MHz NF of 1.85 dB over Frequency Unconditionally Stable Single 5V Supply High OIP3 @ Low Current
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.

Operating temperature is -40C 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 0V to Vs.

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.

1) The tantal capacitor is optional and for bypassing the AC noise introduced from the DC supply. 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.
