The AD7011 is a complete low power CMOS π/4 DQPSK modulator with single +5 V power supply. The part is designed to perform the baseband conversion of I and Q transmit wave- forms in accordance with the American Digital Cellular Tele- phone system (TIA IS-54).

The AD7010 is a complete low power, CMOS, π/4 DQPSK modulator with single +5 V power supply. The part is designed to perform the baseband conversion of I and Q transmit waveforms in accordance with the Japanese Digital Cellular Telephone system. The on-chip π/4 Differential Quadrature Phase Shift Keying (DQPSK) digital modulator, which includes the Root Raised Cosine filters, generates I and Q data in response to the transmit data stream. The AD7010 also contains ramp control envelope logic to shape the I and Q output waveforms when ramping up or down at the beginning or end of a transmit burst. Besides providing all the necessary logic to perform π/4 DQPSK modulation, the part also provides reconstruction filters to smooth the DAC outputs, providing continuous time analog outputs. The AD7010 generates differential analog outputs for both the I and Q signals. As it is a necessity for all digital mobile systems to use the lowest possible power, the device is designed in a low power manner.

The AD7008 is a CMOS DDS Modulator features a single +5 V supply, 32-Bit Phase Accumulator, On-Chip COSINE and SINE Look-Up Tables, On-Chip 10-Bit DAC, Frequency, Phase and Amplitude Modulation, Parallel and Serial Loading, Software and Hardware Power Down Options, 20 MHz and 50 MHz Speed Grades.

1SV266 is a PIN diode produced by SANYO. It is mainly used in VHF, UHF, AGC and other scenarios. This diode has the characteristics of small package, low reverse voltage, low reverse current, and low series resistance.

AD7002 is a LC2MOS GSM Baseband I/O Port from Analog Devices. It has a single +5 V supply, an integrated GMSK modulator, two 10-bit D/A converters, analog reconstruction filters, and power-down modes.
