1.4 Technical data

1.4.1 General HF specification

 Operating frequencies, tolerance

Single channel operation:

op1

= 315MHz (USA, Japan)

op2

= 433.92MHz (ECE)

3-channel operation:

op1

= 314.00MHz / 314.45MHz / 314.9MHz (USA, Japan)

f op2 = 433.47MHz / 433.92MHz / 434.37MHz (ECE)

Temperature shift –20 to +65 C: +/-35ppm

Ageing: +/-10ppm

Remaining deviation after adjustment: +/-2ppm

Voltage dependency and drift XTO: +/-3ppm

Total tolerances remaining after

adjustment of the initial frequency +/-50ppm

1.4.2 Specification of the HF transmitter

 Transmission power EIRP:

ECE*: -14,4dBm….-22dBm

USA/Canada ** -19.6dBm….-24dBm

Japan(TELEC-T244)***: -19.6dBm….-24dBm

* maximum transmission power limit Taiwan : 80.83dbµV/m at a distance of 3m.

With isotopic propagation, the maximum transmission power is –14.4dBm.

** maximum transmission power limit according to FCC section15/Canada RSS-210:

3.75…12.5mV/m in the 260-470MHz range at a distance of 3m

At 315MHz the figure is 6.042mV/m, which relates to a transmission power of –19.63dBm with

isotopic propagation.

*** Use of the USA variant

taken from the new TELEC-T244 Japanese standard

Limit max. 25µW with transmission frequency of up to 315.25MHz, this relates to -16dBm

Use of the USA variant
