1700MHz to 2200MHz High-Linearity,
SPI-Controlled DVGA with Integrated Loopback Mixer
Typical Operating 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, fLO = 95MHz, fLBOUT =
fRF - fLO, and TC = +25°C, unless otherwise noted.)
