Note 2: Recommended operating frequency range. Note 3: f1 = 210.88MHz, f2 = 210.89MHz, Pf1 = Pf2 = -15dBm. Note 4: f1 = 210.88MHz, f2 = 210.89MHz, Pf1 = Pf2 = -50dBm. Note 5: Small-signal gain at 200kHz below the LO frequency will be reduced by less than 0.25dB when an interfering signal at 1.25MHz below the LO frequency is applied at the specified level. Note 6: Guaranteed by design and characterization. Note 7: f1 = 85.88MHz, f2 = 85.98MHz, Pf1 = Pf2 = -15dBm. Note 8: f1 = 85.88MHz, f2 = 85.98MHz, Pf1 = Pf2 = -50dBm. Note 9: Measured at LOOUT with BD = 0 ( ÷2 selected). Note 10: Not available on MAX2316.
