Sorry, ADL5380. Board in question is the ADL5380-EVALZ.
IQ Modulator: ADL5375 (www.analog.com/adl5375)
IQ Demodulator: ADL5380 (www.analog.com/adl5380)
i use ADL5380,but it's so easy to damage,i changed several chips ,then it can work well,
but one month later ,the output power lost more than 10dB, from -2dbm to -18dbm,
and in this situation i changed a capacitor in the RF from balun to ADL5380…
Do the adl5380 demodulator work whit RF freq at 5400MHZ and the LO freq at 5430MHz?
are the I/Q outputs valid 30 MHz outputs in this case?
ADL5380基带输出为50 ohm差分阻抗，但为什么参考电路用的是9：1的巴伦，问过支持，怎么说是什么负载是450 ohm，然后用9：1转，但是手册上的差分输出50 ohm又是什么意思，如果是50ohm，我想用个1：1的转成单端50ohm可以么。 另IQ调制时，用单端转巴伦，1：1的怎么接共模电压
I have a couple of questions regarding the ADL5380:
1. Is there any characterization available for the slew rate of the I and Q amplifier outputs
2. In the case where RFin and LO are close in frequency (seperated by 10KHz) we are noticing the outputs…
in my adl5380 application BB I/Q max freq is 190MHz.
ADL5380 should be connected with either a 2¨1 balun (100Ω -->50Ω) or a 4:1 balun (200Ω-->50Ω)
A microstrip 100Ω differential line of aproax 12cm long connects al5380 with the balun.
I'm looking at the ADL5380 for a multi-channel receiver. Each channel would have its own ADL5380. Channel-to-channel relative phase on the ADL5380 baseband output is important.
First question: Does the ADL5380 mechanism for generating a quadrature…
In my device I want to use the AD8129 after ADL5380. But AD8129: "Differential Operating Range +-0.5 V (input)", and for the ADL5380: "Output Swing (differential 200 Ω load) 2 Vp-p". That is, the output voltage of the ADL5380 is necessary…
