FEATURES
GENERAL DESCRIPTION
Wideband, dual-channel, active downconversion mixers Low distortion, fast settling, IF DGAs RF input frequency range: 690 MHz to 3.8 GHz Programmable baluns on RF inputs For RF = 1950 MHz, IF = 281 MHz, high linearity mode
Voltage conversion gain, including IF filter loss:
- 5 d B to +26.5 d B
Input IP3: 29 d Bm at minimum DGA gain Input P1d B: 12 d Bm at minimum DGA gain SSB NF: 13 d B at maximum DGA gain Output IP3: 40 d Bm at maximum DGA gain Output P1d B: 19 d Bm at maximum DGA gain Channel isolation: 52 d B Differential and single-ended LO input modes Differential IF output impedance: 100 Ω Flexible power-down modes for low power operation Power-up time after enabling channels: 100 ns, typical Programmable via a 3-wire serial port interface (SPI) Single 3.3 V supply High linearity mode: 440 m A Low power mode: 260 m A
