Hittite's New Time-Delay/Phase Shifter Delivers 500° over 8-23 GHz
-- Ideal for Fiber Optic Clock & LO Synchronization Applications
Chelmsford, MA, 11/4/2011 - Hittite Microwave Corporation, the world class supplier of complete MMIC based
solutions for communication & military markets announces the release of the
HMC877LC3 8 to 23 GHz Time Delay/Phase Shifter. The
HMC877LC3 is ideal for clock chain and skew adjustment in 10G-RZ, 40G/100G RZ-DQPSK fiber optic applications.
The
HMC877LC3 is the first Time Delay/Phase Shifter product in the market to provide up to 1.4 UI (500°)
continuously adjustable delay over a wide 8 to 23 GHz frequency range, while maintaining a constant differential
output voltage. The device accepts either single-ended or differential input signals, while providing a 500 to 900
mVp-p programmable differential output swing.
The
HMC877LC3 provides a time delay/phase shift which is linearly monotonic with respect to the differential delay
control voltage, over a ±0.6V tuning range. On chip compensation circuitry ensures an extremely stable
programmable time delay over both frequency and temperature. A high delay control modulation bandwidth (3 dB
rolloff point) of 2.5 GHz combined with single +3.3V operation also make the
HMC877LC3 ideal for phase modulation in military & space, test & measurement and broadband applications.
The
HMC877LC3 complements many of Hittite’s previously released limiting amplifiers, modulator drivers and high
speed logic products to provide a complete solution set for fiber optic and test equipment applications. The
HMC877LC3 is housed in a ceramic 3 x 3 mm SMT package (RoHS compliant), and is fully specified for operation
from -40 °C to +85 °C.
Samples and evaluation PC boards for all SMT packaged products are available from
stock and can be ordered via the company’s e-commerce site or via direct purchase order. Released data sheets are
available on-line at
www.hittite.com.
