NOTES
1
AIN, AIN /BIN, BIN: The AD6600 analog inputs are unconditionally stable and guarantee proper operation over the 70 MHz–250 MHz specified operating range.
Circuit board layout is critical on this device, and proper PCB layout must be employed to achieve specified results.
2
Analog Input 3 dB Bandwidth is determined by internal track-and-hold. The front-end attenuators have a bandwidth of 1 GHz.
3
Measured real and imaginary values using Network Analyzer.
4
Full-scale gain tolerance is the typical variation in gain at a given IF input frequency. The nominal value for full-scale input power is a function of frequency as
shown in previous specification.
5
Full-scale gain tolerance measured at 200 MHz analog input referenced to 6.7 dBm nominal full-scale input power. For the gain measurement test, the input signal
level is set to –6 dBFS. Tuning port bandwidth is set to 50 MHz.
6
Main channel set to full-scale input power. Diversity channel swept from –20 dBFS to –90 dBFS.
7
Measurement includes thermal and quantization noise at 70 MHz analog input. Tuning port bandwidth is set to 50 MHz.
8
Test tones at 160.05 MHz and 170.05 MHz.
9
Measurements at –1 dFBS, –6 dBFS, and –10 dBFS are in highest attenuation mode, RSSI = 101.
10
Each gain-range is checked at ~3 dB from RSSI trip point (not in hysteresis); nominally –16 dBFS (RSSI = 100), –22 dBFS (RSSI = 011), –28 dBFS (RSSI = 010),
–35 dBFS (RSSI = 001).
11
Measurement at –54 dBFS is in the lowest attenuation mode, RSSI = 000.
Specifications subject to change without notice.
