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…
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
Hi, I am using the evaluation board for ADL5380 for a homodyne receiver. My RF and LO signals are 868 MHz, however I am modulating my RF signal using AM modulation and my LF is 1 Hz.
My I and Q outputs are showing the up-converted signal at 1.7GHz, but…
ADL5380的差分阻抗写的50ohm,手册中写的负载200ohm和450ohm跟这个有什么关系，我输出为50ohm，是不是直接通过一个1：1巴伦就可以了。参考图中用9：1巴伦转的，ADL5380基带差分阻抗为50ohm，那经过巴伦变换之后岂不是变成（50/9）ohm了，因为巴伦次级接的ADL5380基带，主级接的后面负载,次级跟主级阻抗比为9：1。
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?
tnx, Luca
Hello Sir/Madam,
I am using ADL5380 eval board for same RF/LO Frequency. I have Given both the Input signals through Splitter for synchronizing the input signals. With the guidance of this forum i have bypassed the output side baluns to pass DC value…
Does the ADL5380 quadrature demodulator have a high band evaluation board? The ADL5380-29A-EVALZ is described as mid band up to 4 GHz. To measure 5.8 GHz, will I need to get the -29A and replace the Johanson Technology 3600BL14M050 balun with the Johanson…
I want to buy a ADL5380-EVALZ, and what should I do if I want to use single-ended LO and single-ended RF?
