High-Linearity, 650MHz to 1000MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
Typical Operating Characteristics (continued)
(Typical Application Circuit, optimized for the 800MHz/900MHz cellular band (see Table 1), C1 = 82pF, C5 = 2pF, L1 and C4 not used,
VCC = 5.0V, PLO = 0dBm, PRF = 0dBm, fLO > fRF, fIF = 160MHz, TC = +25°C, unless otherwise noted.)
