It optimizes system performance while reducing manufacturing costs of transmitters that use symmetric or asymmetric power amplifier designs to efficiently process signals with large peak-to-average ratios. This monolithic RFIC integrates a 90° RF splitter, digita l phase shifters and a digital step attenuator along with a low voltage CMOS serial interface. It can cover a phase range of 87.2° in 2.8° steps and an attenuation range of The PE46120 also features exceptional linearity, high output port-to-port isolation and extremely low power consumption relative to competing module solutions . It is offered in a 32-lead 6 × 6 mm QFN package. The PE46120 is manufactured on Peregrine’s UltraCMOS ® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the perf ormance of GaAs with the economy and integration of conventional CMOS. Peregrine’s HaRP™ technology enhancements deliver high linearity and excellent harmonics performance.

Monolithic Phase & Amplitude Controller Page 8 DOC-54655-6 – (5/2015) www.psemi.com Programming Options Serial Interface The serial interface is a 14-bit serial-in shift register with two parallel-out channel registers RF OUT1 and RFOUT2 buffered by a transparent latch. The 14 bits are comprised of four bits defining the attenuation setting and five bits for the phase shift setting. Channel register RF OUT1 and RF OUT2 selection is determined by the value of the C0 bit contained as part of the 14-bit program word. The serial interface is controlled using three CMOS compatible signals: serial data in (SDI), clock (CLK) and latch enable (LE). The SDI and CLK inputs allow data to be serially entered into the shift register. Serial data is clocked in starting with two spare bits first and then the phase setting LSB. The shift register must be loaded while LE is held LOW to prevent the internal channel register values from changing as data is entered. The LE input should then be toggled HIGH, latching the new data into the PE46120. SDO is a clock delayed reply of the user’s input SDI command for functional confirmation. Phase shift and attenuation setting truth tables are listed in Table 6 and –Table 7. The serial timing diagram is illustrated in Figure 2 and associated AC characteristics are listed in Table 10. Power-up Control Settings The PE46120 will power up in one of two default states depending upon the setting of the default state (DS) pin, as defined in Table 8 and Table 9. No specific signal sequencing is required for the default state to be set and active once V DD is applied.

The alternate unused pin needs to be left floating. 2) SDOs are independently buffered outputs of the same signal. 3) RF pins 4, 5, 17 and 18 must be at 0 VDC. The RF pins do not require DC blocking capacitors for proper operation if the 0 VDC requirement is met. 4) Pin 19 must be grounded for proper function. 5) Must be active low for normal SPI operation. Logic high programs 0 dB attenuation setting and 0° phase setting. Setting back to logic low returns to the previously programmed state. 6) Pin has an internal 100 k Ω pull-up resistor.
