4.2 Characteristics for IF Band Tuning
Although the ICs in this line-up were developed as various types of buffer amplifiers for cellular or cordless
telephones, the recommended operating frequency range is 100 to 1900 MHz, and these ICs can also be used at IF-
band frequencies. For this section, the characteristics were measured for input/output tunings at operating
frequencies of 130 MHz and 240MHz, which are used frequently in the IF band. Table 4-2 shows the measurement
results, and Figure 4-2 shows the measurement circuits. When these ICs were used in the IF band, the power gain
was higher and the isolation was better than when they were used in the 1 to 2 GHz range.
