MAX1470 Maxim, MAX1470 Datasheet - Page 3

• Manufacturer Part Number: MAX1470
• Description: 315MHz Low-Power / +3V Superheterodyne Receiver
• Manufacturer: Maxim

AC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, all RF inputs and outputs are referenced to 50Ω, V
erwise noted.) (Note 1)
Note 1: Parts are production tested at T
Note 2: BER = 2E-3, Manchester encoded, data rate = 4kbps, IF bandwidth = 350kHz.
Note 3: Input impedance is measured at the LNAIN pin. Note that the impedance includes the 15nH inductive degeneration con-
Note 4: Guaranteed by production test.
