HTR Rubber Sheet Absorber is a series of elastomeric absorbers which, typically, absorb -5dB ~ -51dB of normally incident energy at a discrete frequency between 10MHz ~ 6000MHz.

Based on the tuned frequency, HTR absorber is designed with thickness in the range of 0.1¡B0.2¡B0.3¡B0.4¡B0.7¡B0.9¡B2 and 4mm. We also provide special design for the customers¡¦ requirement of the frequency, absorbing rate, etc.

 HTR series are newly-developed product that is very efficient way to solve the EMI problem of LCD for notebook¡Bcomputer , electronic device ,wireless communication device , and even new-generation ultra-thin or mini-portable computer/PDA.Especial a small piece of HTR-3G series can replace the conductive coat¡Bmetal shielding etc, by sticking on these place needed to solve the EMI/RFI/EMC problem and meet strict SAR rule.

 The materials are normally provided in 25cm x 25cm which can be readily cut to any desired size. The nomarl temperature resistance is -400 C ~ +900C. 

Applications:

  • EMI Reduction for Antennas and Electronic Systems (such as LNBs for Satellite System).
  • Antenna Pattern Shaping and False Echo Reductions.
  • The Radiation Hazard Protection.
  • To paste on electric circuit¡Bconnector¡Bcable socket ¡Bflat cable.
  • To suppress and absorb attenuate electromagnetic waves and noise out through electric circuit.
  • Being available at LCD display, cable modem or wrap cable and wire, also any noise source.
  • Solving for third/ fourth generation (3G/4G) Handset RFI problem.
  • Wireless communication equipment¡BBlue tooth device.

Application Example of HTR series:
(1) HTR for LCD¡¦s EMI problem
The HTR series can be used as the figure shown. The HTR series used to replace the ferrite tile clamp on FPC I/O connector. The conductive coat is taken off near the connector. Such arrangement can reduce radiation at least 5 dB to 12dB for whole system. Since the thickness of HTR-03B is 0.3mm, the total thickness of HTR-03B clamp is 0.6 mm only. This means there is no space problem now.  The HTR series also can cut to small pieces and paste on the backside of driving IC of LCD to solve EMI problem.
