Amplifier R&S PMU901 R&S® TMU9 Design and Function R&S PMU901 5 Amplifier R&S PMU901 5.1 Design and Function R&S PMU901 5.1.1 Device Purpose and Overview The R&S PMU901 amplifier is a broadband unit that operates as a power amplifier in the frequency range from 470 MHz to 862 MHz with the following TV standards: ● digital (DTV) standards: DVB‑T/H, DVB‑T2, ATSC, ATSC Mobil, ISDBTB ● analog (ATV) standards: ATVc (combined) B/G, D/K, K1, M/N, I, I1 It is based on the BLF888 transistor from NXP.
Amplifier R&S PMU901 R&S® TMU9 Design and Function R&S PMU901 frequency of the transmitter or the wrong operating mode is configured, the amplifier remains switched off and signals FREQ_FAIL. Control and monitoring The amplifier is operated via the transmitter control unit only. Module A1 (amplifier control board), which operates independently of power and frequency band and is also used in other TX9 amplifiers, is responsible for the monitoring and control functions as well as CAN bus connection.
Amplifier R&S PMU901 R&S® TMU9 Design and Function R&S PMU901 ● A6, A7: Adaptor board 1, adaptor board 2 (standby) The entire amplifier unit is on the top side of the amplifier. Fig.

Fig.
Amplifier R&S PMU901 R&S® TMU9 Design and Function R&S PMU901 ● The power supply unit has its own heat sink which also dissipates heat from the power supply unit to the flow of cooling air inside the amplifier. ● Part of the cooling air also flows through the power supply unit circuitry in order to cool the components.

It goes though the following steps in the preamplifier and driver.
Amplifier R&S PMU901 R&S® TMU9 Design and Function R&S PMU901 ● The signal leaves the preamplifier and is fed to the input of the driver amplifier via the cable W145x. This input consists of two single‑ended LDMOS transistor stages which are interconnected by means of 90° jumpers. The two transistor halves of the BLF888B push‑pull transistor are used for this purpose. ● The cable W145x is also used for phase adjustment (in the case of design modifications or for tolerance adjustment).
Amplifier R&S PMU901 R&S® TMU9 Design and Function R&S PMU901 5.1.4.4 Power Control To ensure that the required power is always present at the amplifier output, the level tolerances at the following points are adjusted by means of a power control circuit. ● at the amplifier output ● at the entire RF amplifier stage During power control, a control amplifier which is on the amplifier board (module A2, preamplifier section) is supplied with an actual voltage and a nominal voltage.
Amplifier R&S PMU901 R&S® TMU9 Design and Function R&S PMU901 power detector PWR_OUT, the reflected power test point takes over power control. The control amplifier supplies the control voltage V_REG as the output quantity and this voltage is fed to the amplitude regulator in the preamplifier. Additionally, the REFL_OUT signal is acquired at the reflected power test point. This signal together with the PWR_OUT signal (forward power) is used for VSWR indication at the amplifier output. 5.1.4.
Amplifier R&S PMU901 R&S® TMU9 Design and Function R&S PMU901 A soft start is performed as soon as the input signal returns. The selected threshold is such that the amplifier can be reliably operated across the entire temperature range in all permissible operating modes, even at the lower tolerance limit of the RF_IN input signal at X10. Output power limitation The output power is set by means of the VREF_PWR signal.
Amplifier R&S PMU901 R&S® TMU9 Design and Function R&S PMU901 ● With major reflection above reflection threshold 2 (s = 2), the power is briefly cut off completely first of all; a soft start is performed immediately afterwards. If any reflection remains, the amplifier protects itself by reducing the output power. The time constant selected for the shutdown is such that damage to the amplifier is prevented in the case of total reflection and at all phase angles of the reflection at X2.
