Typ. 150 Rated Output Power (CW) Max. Unit 162 MHz 7 W 0 dBm The typical rated power of 5.5W is quoted for a supply voltage of 7.2V. Minimum rated power is 4.4 5.5 for a supply voltage of 6V (See note 1) Input Power for Rated Output CW Power -5 IMD Products at Rated Output Power See Note 2 -25 dBc Minimum Output Power See Note 3 0.1 W -10 dB -39 dBm -33 dBm Input Return Loss Conducted emissions below 1GHz not including `Low' Frequency Conducted Emissions harmonics of the input frequency and intermodulation distortion products. Conducted emissions between 1 - 4 GHz not `High' Frequency Conducted Emissions including harmonics of the input frequency and intermodulation distortion products. Rejection of 2nd Harmonic The harmonic level is measured relative to the (440 - 444MHz) power at the fundamental frequency. Rejection of 3rd and higher order The harmonic level is measured relative to the harmonics power at the fundamental frequency. Disabled Output Power Reduction With PA disabled, relative to rated output power. Time to Reach Disabled Output Power Time to switch once the control signal has come Reduction State within 100mV of its final logic state. PA Enable Vih Module enabled PA Enable Vil Module disabled Supply current at rated CW output power Standby Supply Current No RF drive VSWR load mismatch tolerance Unconditionally stable under all phases 25 dBc 35 dBc 80 dB 1.0 2.0 ms V 0.8 V 2 A 1 mA 5:1 -- Notes 1. Output power at 6V measured with maximum Input power for Rated Output CW Power. 2. All Intermodulation (IMD) specifications are quoted for a two-tone test. The tones are of equal amplitude with 600Hz frequency spacing. The amplitude of each tone is 6dB below the rated PEP to give a composite output power of 5.5W PEP. The level of IMD is measured in dBc relative to one of the two fundamental tones at the output of the power module. 3. The power delivered by the power amplifier module is controlled by varying the input drive level. The output power is continuously variable over the quoted power range, i.e. the rated output power to the specified minimum power. Semelab plc. Telephone +44(0)1455 556565. Fax +44(0)1455 552612.
