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.

Operating temperature is -40°C to +85°C.
1) OIP3 is measured with two tones at an output power of 5 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.

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.
