Internally Matched LNA Module

Features

Description

The plerow^TMALN-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.

1) OIP3 is measured with two tones at an output power of 10 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 V_S.

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.

Application Circuit

Capacitor

OUT

ALN

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.
