Part Number: AFE7225EVM Other Parts Discussed in Thread: TRF370333 , AFE7225 Can you explain the rationale behind the filter chosen between the AFE7225 and the TRF370333? I've referred to SLA399, section 4.1.3, and it has a substantially different solution…
Other Parts Discussed in Thread: TRF370333 , TRF370315 hello
I'm Alber as a FAE in Arrow Korea.
Generally, TRF370315(or TRF370333) used to as up-converting device from IF(or Baseband) to RF.
But, my customer asked about this device to use for…
1. BBIN(22pin) / BBIP(21pin) / BBQN(9pin) / BBQP(10pin) => Condition???
RJH>> Make sure common mode of 3.3V is maintained on the BB input lines. This device is optimally interfaced with TI's current sink DACs.
2. Power Supply condition ???
RJH>…
Other Parts Discussed in Thread: TRF3765 , TRF370333 Hello All,
Please advise if there is any advantage by feeding the LO inputs of TRF370333 differentially. In datasheet there is no reference regarding this issue. The customer is using TRF3765 as LO…
Other Parts Discussed in Thread: DAC5687 , TRF370333 Hello,
I am using the TRF370333 I\Q Modulator in a low-IF radio architecture as the final up-mixer before the RF. The BPSK modulated complex single-ended I\Q signal which comes from the DAC5687 is…
Other Parts Discussed in Thread: TRF370333 , TSW3003 Hi,
I am working on a design using the TRF370333 modulator and would like to use a single-ended LO input. The datasheet says in that case to terminate the LON pin with 50 ohms to ground but does…
Other Parts Discussed in Thread: DAC5688 Team,
My custoemr is wondering how much unadjusted LO feedthrogh spec of min. and max on following condition.
datasheet shows ionly typical value.
1. LO Freq: 2137~2227MHz
2. LO Power: 0dBm

Part Number: AFE7222 Other Parts Discussed in Thread: TRF371109 , TRF371135 , , TRF370333 I have a query regarding the connection of IQ outputs from TRF371109 and TRF371135 to form a single IQ channel (one differential I and one differential Q) for sampling…
Pradeep:
Be careful. The reference schematic is proper for interfacing to the TRF370333 modulator. If that is the intent, then the circuit is good. There are a couple of additional resistors that impact the AC load so that compliance voltage is kept…
Part Number: AFE7222 Other Parts Discussed in Thread: TRF370333 , Hello!
I have question regarding connection of baseband signal to quadrature modulator/demodulator. In PCB mounting the IC have several layout, and I can't connect output of demodulator…
