Duplex circular polarizer is a broadband circular polarizer. Because the transmitter and receiver can share a circular polarizer in a different frequency receiving and transmitting communication system, it is called a broadband circular polarizer. It can realize line to circular polarization conversion within 20%, 40% bandwidth or even octave bandwidth, and has good circular polarization performance. The axial ratio is less than 2dB, 3dB and 5dB respectively. The frequency covers 2-40 GHz. The circular polarizer adopts the combination of positive and negative phase shifting units, which makes the phase shift become smooth with the change of frequency, so as to achieve the effect of 90 ° wide band phase shifting.
For the circular polarizer, the parameter index to be considered is mainly the axial ratio, specifically the shift phase difference.Another important parameter is standing wave, which reflects the matching degree.
Insertion loss is also an important parameter of the circular polarizer. The insertion loss of the circular polarizer not only marks the loss of transmission through the circular polarizer, but also increases the noise temperature of the antenna. For the feed source, it is a noise source that cannot be ignored. As a part of the feed source, the circular polarizer is also a noise source. Therefore, it is necessary to strictly control the insertion loss of the circular polarizer. The insertion loss of the feed is also related to the frequency band used. The lower the frequency band, the smaller the insertion loss value.

1. Q: Are you a manufacturer or a trading company?
Yes, we are the manufacturer. Our company has 15 years of professional experience in the field of telecommunications and can design and manufacture various microwave waveguide components, coaxial components, antennas and other telecommunications components for the global market.
2. Q: How do I place an OEM order?
A: 1. We will manufacture these products according to the mechanical drawings you provide. Some minor changes may occur during the production process to ensure that we can meet your electrical specifications. Or we can take the first set as a sample to see if it meets your specifications. After communication, the buyer and seller reached an agreement on product details, packaging, purchase quantity, unit price, delivery time, payment terms, etc.
2. The buyer sends a formal PO (Purchase Order) or the seller sends a formal PI (proforma invoice) with detailed terms and conditions.
3. Q: How to solve the after-sales service problem?
After receiving the goods, if you have any dissatisfaction or other problems, please contact us as soon as possible, we will give you a quick response and reasonable solution.
4. Q: How long is your delivery time?
A: Usually 7-15 business days after receiving 100% payment. For bulk orders: 15-35 working days after receipt of deposit.
5. Q: How do I get samples?
A: We need to receive your payment before we can send the sample to you. After the customer confirms the order, we will reduce the sample cost. However, if you are a regular customer of ours, we can send you a sample and then deduct it from your account on the next transaction.
6. Q: What are your payment terms?
A: For small batch orders or urgent orders, you can choose PayPal, Western Union, escrow for the convenience of buyers, 100% payment before delivery; For large orders: 30%/50% of T/T as deposit, balance before shipment.
7. Q: What about the warranty?
