BGB741L7ESD: Broadband MMIC LNA for application from 300MHz to 5GHz

BGB741L7ESD: Broadband MMIC LNA for application from
300MHz to 5GHz
The MMIC LNA BGB741L7ESD from Infineon Technologies is a high performance
broadband amplifier for wireless solutions from 300MHz up to 5GHz.
Built up with Silicon Germanium (Si:Ge) technology, the BGB741L7ESD offers an excellent
noise figure over broad frequency band. The biasing and stabilization circuits built inside the
BGB741L7ESD reduce the number of external parts down to 6 and make the BGB741L7ESD
interesting for compact and high performance LNA designs.
The component can be used from 1.8V until 4.0V and from 5mA to 30mA.
Furthermore, this device includes an integrated ESD protection circuit on chip which protects
the device upto 4.0kV at the input pin and 2.5kV at the output pin (according to Human Body
Model). A CMOS-technology compliant power-on/off function is also integrated in the device.
For environments more sensitive to ESD discharges, the device can be strengthened by
using an additional ESD diode at the RF input of the circuit (ESD0P2RFL ESD diodes series
from Infineon Technologies for example). The component will be enhanced against stronger
ESD aggression potentially caused by non protected devices (like antenna modules).

Application Information
This application note presents the performances of the BGB741L7ESD in a broadband mode
from 300MHz to 5GHz. Thus, this LNA fits for applications like UHF, ISM bands, GPS,
UMTS, WLAN 2.4GHz and WiMax upto 3.8GHz.
The following application diagram (please see the figure 2) shows where the BGB741L7ESD
can be used on a transmission/reception signal chain.
Figure 2
Application diagram of the BGB741L7ESD for 300 MHz to 5GHz applications.
This document provides the results for several bands (UHF, GPS, WLAN 2.4G, WiMax) in
relation with the current/voltage biasing (Please see the Table 2, 3, 4 and 5 below).
Please note that the gains in-band (Table 2, 3, 4 and 5) are referenced to the lowest gain
measured in the described frequency band. The related 3 rd order intercept point and -1dB
compression point are measured at the frequency point described in the comments. These
measurements are measured in-band without out-of-band jammer signalsThe device is
unconditionally stable from DC until 10GHz.

Bias Current/Voltage Configuration
Figure 4
Characteristics current/voltage in function of the resistor Rext for the BGB741L7ESD
biasing.
This graph shows how to find the right external resistor Rext (see Figure 1) to get the working
point needed for the desired application. The biasing point is important to set-up since, it
affects all the signal parameters like S-parameters, linearity in Power (P1dB), linearity in
frequency (IIP3) and the Noise generated by the circuit (Please refer to the table 2,3,4 and 5
for performances comparisons) .
