FM_IQ and FM_I modes are not available on MAX2309.

Recommended operating frequency range. Contact factory for operating frequency outside this range.

f1 = 183.7MHz, f2 = 183.71MHz, Pf1 = Pf2 = -15dBm.

f1 = 183.7MHz, f2 = 183.71MHz, Pf1 = Pf2 = -50dBm.

Guaranteed by design.

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.

f1 = 183.7MHz, f2 = 183.71MHz, Pf1 = Pf2 = -23dBm.

f1 = 183.7MHz, f2 = 183.71MHz, Pf1 = Pf2 = -55dBm.
