Schedule 1 Notional receiver performance level

(subsections 5(1) and 13(2))

1 Notional receiver performance level

(1) The notional level of performance for a 700 MHz band receiver in relation to an unwanted signal from a radiocommunications transmitter operated under an apparatus licence, relates to: (a) adjacent channel selectivity; and (b) receiver intermodulation response rejection; and (c) receiver blocking. (2) This level of performance is taken to be a notional receiver performance level with reference to a radiocommunications receiver sensitivity level of: (a) -96 dBm measured within a 5 MHz rectangular bandwidth that is within the frequency band of the spectrum licence, for a receiver with a bandwidth of less than 20 MHz; and (b) -89 dBm measured within a 20 MHz rectangular bandwidth that is within the frequency band of the spectrum licence, for a receiver with a bandwidth equal to or greater than 20 MHz. (3) A notional radiofrequency selectivity for the radiocommunications receiver (between the antenna and the antenna connector of the equipment) may be assumed to be at least equal to: (a) 2 + 70∙log10[1+(2∙FreqOffset/5)1.5] dB for FreqOffset ≤ 2.5 MHz; (b) 2 + 70∙log10[1+(2∙FreqOffset/5)2] dB for 2.5 MHz < FreqOffset ≤ 9 MHz; (c) 82 dB for FreqOffset > 9 MHz;

where FreqOffset is the smallest frequency difference between either the upper or lower limits of the frequency band of the spectrum licence under which the receiver operates and any frequency outside that frequency band.

(4) For the purposes of verifying these performance parameters of the notional radiocommunications receiver, the comparison of the sensitivity level and the unwanted signal is defined at the antenna connector port of the receiver unit. In this way, the performance of the entire receiving system, including the receiver unit and external filters, is taken into account. (5) All frequency offsets are specified with reference to the upper and lower limits of the frequency bands of the spectrum licence under which the receiver operates.

2 Adjacent channel selectivity

(1) In this instrument, adjacent channel selectivity means the measure of the ability of a radiocommunications receiver to receive a wanted signal without exceeding a specified degradation in output due to the presence of an unwanted signal from an adjacent channel. (2) An adjacent channel selectivity of greater than or equal to the following relative figures for respective channel bandwidths is required:

Note: The values in the table above are the ratio between the received unwanted signal power in the adjacent (interferer’s) channel and the receiver’s sensitivity level.

3 Intermodulation response rejection

(1) In this instrument, intermodulation response rejection means the measure of the ability of a radiocommunications receiver to receive a wanted signal in the presence of two or more unwanted signals with a specific amplitude and frequency relationship to the wanted signal frequency. (2) An intermodulation response rejection greater than or equal to the following values for each out-of-band signal is required:
