Application Information
4.1
470 MHz–860 MHz Application
This application was designed to provide NF < 1.4 dB, S21 gain > 21 dB, OIP3 of 10 dBm with return
losses better than -10 dB at 470 MHz and NF < 1.3 dB, S21 gain > 17 dB, OIP3 of 13 dBm at 860 MHz.
This is a broadband application with application to UHF. The performance can be further optimized for
narrowband applications such as RKE at the lower frequency, or wireless security at the higher frequency.
Typical performance that can be expected from this circuit at 2.7V is listed in Table 17 .
Figure 14 shows the 470 MHz–860 MHz schematic with package pinouts and circuit components.
