1700MHz to 2200MHz High-Linearity, SPI-Controlled DVGA with Integrated Loopback Mixer

Maxim Integrated 

1700MHz to 2200MHz High-Linearity,

SPI-Controlled DVGA with Integrated Loopback Mixer

Typical Operating Characteristics

(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.)
