The MRFIC2404 is a single–stage class A GaAs amplifier in a low–cost
8 lead plastic package designed to drive the MRFIC2403 power amplifier for
use in the 2.4 to 2.5 GHz Industrial–Scientific–Medical (ISM) band. The design
is optimized for 5.0 Volt operation at 2.45 GHz but is usable from 2.0 to 3.0 GHz
in applications such as telemetry and Multichannel Multipoint Distribution
System (MMDS) wireless cable TV systems. Performance is suitable for
frequency hopping or direct sequence spread spectrum as well as single–frequency applications.

The MRFIC2404 is a single–stage GaAs amplifier
designed for exciter applications such as driving the
MRFIC2403 power amplifier. The 4.3 dB noise figure, 17 dB
gain and +5.0 dBm power output at 1.0 dB gain compression
make the MRFIC2404 suitable for high–performance
receiver IF application, Multichannel Multipoint Distribution
System (MMDS) applications, telemetry and other applications in the 2.0 to 3.0 GHz range.
The characterization curves show typical performance in
the 2.0 to 3.0 GHz range in the circuit shown in Figure 1. This
circuit was also used to derive the device impedance shown
in Table 1. The amplifier input is matched to 50 W while the
output requires about 3.3 nH series inductance for best

match at 2.45 GHz. The VDD supply line should be bypassed
as close to the chip as possible to avoid low frequency
oscillations. Power supply “stiffening” and digital transient
bypassing in the form of electrolytic of tantalum capacitors
should be added.
The device can be put into a reduced current “sleep” mode
by 5.0 Vdc to the V
bias
pin.
EVALUATION BOARDS
Evaluation boards are available for RF Monolithic Integrated Circuits by adding a “TF” suffix to the device type.
