700MHz to 1200MHz High-Linearity,
SPI-Controlled DVGA with Integrated Loopback Mixer
Typical Operating Characteristics (continued)
(MAX2058 Typical Application Circuit, VCC = +4.75V to +5.25V, digital attenuators set for maximum gain, 700MHz ≤ fRF ≤ 1200MHz,
40MHz ≤ fLO ≤ 100MHz, TC = -40°C to +85°C. Typical values are at VCC = 5.0V, PIN = 0dBm, fRF = 940MHz, fLO = 45MHz, fLBOUT =
fRF - fLO, and TC = +25°C, unless otherwise noted.)
