TC4-LP Embedded Modem Module
HIGHLIGHTED FEATURES

TC4-LP HF & V/UHF Modem, ALE and Voice Module

The TC4-LP is a high-performance LF, HF and V/UHF modem, ALE and voice module. The TC4-LP is optimised for low power consumption. The module is suitable for integration into LF, HF and V/UHF radios and other communication equipment. The TC4-LP is recommended for new designs.

The TC4-LP offers the same functions found in the TC4, including HF/VHF/UHF data modems, 2G ALE and 3G ALE/STANAG 4538. In addition, the TC4-LP hardware can host the RapidM EF-256 embedded functions, which include Secure Digital Voice (SDV) and AES-256 Encryption.

For V/UHF operation the maximum data rate is 128000 bps in a 24 kHz audio channel.

The operation of the TC4-LP is determined by the selection of one of the following software packs:

  • M1: LF and HF Modem (Including ISB, Up to 19200 bps & 110C 6 kHz up to 32000 bps)
  • M2: HF Modem (SSB, Up to 9600 bps)
  • M3: HF Modem (SSB, broadcast, Up to 2400 bps)
  • M4: HF Modem (SSB, S4539, Up to 9600 bps)
  • L1: V/UHF Modem (24 kHz, Up to 128000 bps)
  • L2: V/UHF Modem (12 kHz, Up to 64000 bps)
  • L3: V/UHF Modem (6 kHz, Up to 32000 bps)
  • L4: V/UHF Modem (3 kHz, Up to 16000 bps)

The following software options are also available:

  • 2G ALE Controller Software Option
  • STANAG 4538 (3G ALE) Modem Option
  • Digital Voice (2400 bps)
  • 56-bit Encryption (Digital Voice and Data)
