Response to FCC correspondence Ref. No. 1676 1. Grant corrected. 2. The test laboratory has made the following argument: “According to Part 2.1055(a)(2) it specifies the temperature range as -20 to +50 for "equipment to be licensed for use above 952 MHz at operational fixed stations in all services". Since this is a PCS base station transmitter, wouldn't this range be appropriate?” 3. New internal photos exhibit has been uploaded. Barry C. Quinlan Certification Manager Curtis-Straus TCB

From the block description the output power of the final stage is > 700Watts. Please confirm that this is only a 20 watt transmitter. [Tom Tidwell] Yes, the maximum output per carrier is 20 W. The maximum number of carriers per FA is 3. Therefore the maximum power output per FA is 20 x 3 = 60W. Each FA represents a transmit antenna. > > 3. The FCC has requested that antenna spurious emissions measurements be > made at the highest and lowest power settings available. Please provide > antenna spurious measurements for the lowest power setting. [Tom Tidwell] There is no minimum power output in practical application. The installation will always be 20 W for each carrier. There can be 1 - 3 carriers, making the rf power output 20 - 60W. Each carrier is transmitted by a single transceiver module within the BTS. Back in May we performed testing for a system that is identical except for modulation parameters. The FCC ID. of the previous approval is NP8-SCBS-319L.
