DESIGN AND APPLICATIONS INFORMATION
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 applica-
tions 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
W in Table 1. The amplifier input is matched to 50 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 Vbias pin.
EVALUATION BOARDS
Evaluation boards are available for RF Monolithic Inte-
grated Circuits by adding a “TF” suffix to the device type.
