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.

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 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
