For simple BPSK, you can design the level shifter circuit to reduce the amplitude of the CMOS output to appropriate bias level of 0.5V VCM with the proper swing, and I agree you can achieve the interface requirement.
The design of the TRF3705 has…
Part Number: TRF3705 Other Parts Discussed in Thread: TRF370417 Hi Team,
The TRF3705 IQ modulator datasheet states that its 1-dB input frequency bandwidth is 1000MHz. Does this IQ modulator output RF signal with a bandwidth of up to 2000MHz?
Part Number: TRF3705 Q1
We intend using the TRF3705 in an application where the baseband signal is only about 50kHz and coming from a micro via some circuitry. All the examples show 50R resistor to ground on these inputs. In our application burning 4…
Part Number: TRF3705 Other Parts Discussed in Thread: DAC34H84 , DAC38J84 Hi team,
My customer have few questions about TRF3705:
1. the OIP3 data in our datasheet is SCL(single carrier level ) or DCL
2. Can they optimize sideband suppression by adjusting…
Part Number: TRF3722 Other Parts Discussed in Thread: DAC38J84 , , TRF3705 Hi,
I am measuring fairly high odd order harmonics on the output of both TRF3705 and TRF3722 on the TSW3XJ8X development board. The peak power of the harmonics is around 5 dB less…
Part Number: TRF3705 Other Parts Discussed in Thread: TRF37T05 , HI
This is HS KOH in WS.
I have question.
I think TRF3705 and TRF37T05 are simillar to specification.
What is the difference between TRF3705 and TRF37T05.
Please let me know.
Part Number: TRF3705 Other Parts Discussed in Thread: DAC3482 Hello
I'm Alber as a FAE in Arrow Korea.
My customer use DAC3482 & TRF3705.
My customer has a question about TRF3705 Input/Output Level as aspect of RF Level.
IQ Modulator has 4 input…
Part Number: TRF3705 Hi Team,
One of my colleagues is looking for the de-embedded S-parameters for the TRF3705. I found this post: but it doesn't seem to match this app note:
Do they need to be de-embedded?
Also, was the gain set to high or low on…
Part Number: TRF3705 Hi Team:
Could you help me to check how to calcultae the case temperature when the TRF3705 junction temperature is 125 degree?
In the datasheet only have Theta JC, don't have power consumption and efficiency. Could you help me to…
Part Number: TRF3705 Other Parts Discussed in Thread: DAC38J84 DAC38J84 + TRF3705
My design is almost a copy of EVM：
DAC38J84 + LPF550MHz + TRF3705,DAC output is quite clean:
with LO = 800MHz,TRF3705 output:
