Ericsson RRU 2219B8a — 900 MHz Band 8 Remote Radio Unit (2T2R)

1) Product overview

The Ericsson Radio 2219 family is a compact outdoor macro RRU platform supporting multi-standard GSM/WCDMA/LTE operation with 2T2R and up to dual-power amplifiers per unit. The B8/B8A variants target Band 8 (900 MHz) macro coverage and capacity upgrades. 

2) Frequency & RF characteristics (B8A)

• Operating band: 3GPP Band 8 (900 MHz) — typical UL 880–915 MHz, DL 925–960 MHz (country plans vary). 

• MIMO / paths: 2T2R (2×2 MIMO). 

• Output power (B8/B8A published figures): field sheets list up to 2 × 60 W for 900/2100 MHz in the 2219 family; 1800 MHz variants are listed up to 2 × 80 W. Always confirm the exact PA rating on the unit nameplate. 

• Note: Some reseller pages show lower or inconsistent power for certain sub-revisions. Treat 2×60 W (B8) as a conservative planning figure and verify on receipt.

3) Interfaces & features

• Antenna ports: 2 × 4.3-10 (female). 

• Front-haul (to baseband): CPRI SFP slots (2 ports) supporting 2.5/5/10 Gb/s line rates (exchangeable SFP). 

• External alarms: 2 inputs (DIN 14).

• RET support: RET 2.0; TMA support noted on field sheet. 

• Mounting: one-bolt/rail system design across 2219 family; supports pole/wall/rail vertical mounting. 

4) Mechanical, power & environment

• Weight: ~17 kg; volume ~17 L (typical for 2219 B8). 

• Supply: −48 V DC (2-wire), telecom ground lugs provided. 

• Enclosure: outdoor weather-sealed macro RRU chassis (family description). 

5) System integration

• Compatible basebands: Ericsson Baseband 5216/6630/6648 and other ERS/RBS units over CPRI. 

• Standards: typically deployed for LTE 900, with backward support for GSM 900 and selected WCDMA configurations (license/software dependent). 

• Receiver expansion: the 2219 family can be paired with Radio 0208 to increase receive branches (2→4) where required. 

6) Identification & ordering (B8A evidence)

• Variant: Radio 2219 B8A (Band 8).

• Observed KRC part number: KRC 161 618/1 for B8A in channel listings; other B8 listings show KRC 161 619/1 and KRC 161 670/1 (B8). Always verify the exact KRC on the front label. 

7) Acceptance checklist (recommended)

1. Nameplate check: confirm B8A marking and KRC PN against PO. 

2. CPRI link test: validate optical power and line rate (2.5/5/10 Gb/s) to baseband. 

3. RF verification: measure per-path output power, VSWR/PIM, and RET control. 

4. Environmental seal/ground: inspect outdoor gasketing and dual ground lugs. 

Notes on data consistency

• Power ratings for 2219 B8/B8A vary by sub-model and source. The 2×60 W figure for 900 MHz is widely cited in field sheets; if your tender demands exact wattage, request a photo of the unit nameplate or Ericsson’s specific release note for that KRC. 

• General family specs (2T2R, mounting system, macro outdoor design) are consistent across Ericsson’s Radio 2219 documentation.
