- PN KRC118045/1; −48 V DC nominal; −38.0 to −58.5 V DC operating range; 15/16 A recommended fuse/circuit breaker
For PN KRC118045/1. - Technologies
- PN KRC118045/1; Active radio: GSM, WCDMA and LTE; passive part is an antenna, not an additional radio
For PN KRC118045/1. - RF output power
- PN KRC118045/1; Without HWAC: 20 W total (2 × 10 W); with HWAC: 60 W total (2 × 30 W)
For PN KRC118045/1. - Bandwidth
- B3: IBW 2 × 20 MHz; operational bandwidth 2 × 20 MHz; conditions: [19] Radio supports Virtual IBW up to 40 MHz. | [44] For GSM: The instantaneous bandwidth is limited to 15 MHz. | [7] Operational bandwidth is the actual bandwidth allocated for carriers.
- Capacity
- PN KRC118045/1; With license: up to 8 GSM carriers, 4 WCDMA carriers or 4 LTE carriers on the active B3 radio
For PN KRC118045/1. - Synchronization
- PN KRC118045/1; When operated over its documented classic CPRI interface: CPRI slave synchronization; the radio recovers the incoming CPRI bit clock for radio/link transmission and receives time information from the REC/Baseband
