LTC5588-1
TYPICAL PERFORMANCE CHARACTERISTICS VCC = 3.3V, EN = 3.3V, TA = 25°C, LOP input
Output
AC-terminated with 50Ω to ground, BBPI, BBMI, BBPQ, BBMQ inputs 0.5VDC, and 1VP-P(DIFF), baseband input frequencies = 4.5MHz
and 5.5MHz for OIP3 and OIP2, or else baseband input frequency = 100kHz, I and Q 90° shifted, lower sideband selection, LINOPT pin
floating, unless otherwise noted. Test circuit is shown in Figure 8.
