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 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 Vbias pin. EVALUATION BOARDS Evaluation boards are available for RF Monolithic Inte- grated Circuits by adding a “TF” suffix to the device type. For a complete list of currently available boards and ones in development for newly introduced product, please con- tact your local Motorola Distributor or Sales Office. |
