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 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.
· S21 = 20.2 dB @ 824 MHz
= 19.8 dB @ 849 MHz
· NF of 0.60 dB over Frequency
· Unconditionally Stable
· Single 5V Supply
· High OIP3 @ Low Current

1) OIP3 is measured with two tones at an output power of +0 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.
Solder Stencil Area
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 or MLC (Multi Layer Ceramic) 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. The ca-
pacitor should be placed as close as possible to Vs pin and be connected directly to the ground plane for
the best electrical performance.
2) 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 includ-
ed inside the ALN 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 fre-
quency.
