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

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)

Note 1: All limits include external component losses. Output measurements taken at RFOUT or LBOUT ports of the Typical

Application Circuit.

Note 2: Operating outside this range is possible, but with degraded performance of some parameters.

Note 3: Compression point characterized. It is advisable not to continuously operate the VGA RF input above +15dBm.

Note 4: Input RF source contribution to spurious emissions (Agilent ESG 4435B, PSA E4443A): 200kHz = -39.2dBc,

400kHz = -73.5dBc, 600kHz = -83.2dBc, 1.2MHz = -85.7dBc

Note 5: See the Applications Information section regarding effective attenuation range.

Note 6: No SPI clock input applied.

Note 7: Guaranteed by design and characterization.
