Maxim Integrated 

1700MHz to 2200MHz High-Linearity,

SPI-Controlled DVGA with Integrated Loopback Mixer

AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2059 Typical Application Circuit, VCC = +4.75V to +5.25V, digital attenuators set for maximum gain, 1700MHz ≤ fRF ≤ 2200MHz,

40MHz ≤ fLO ≤ 100MHz, TC = -40°C to +85°C. Typical values are at VCC = 5.0V, PIN = 0dBm, fRF = 1850MHz, PLO = -6dBm, fLO =

95MHz, fLBOUT = fRF - fLO, and TC = +25°C, unless otherwise noted.) (Note 1)
