Integrated mixer oscillator PLL for satellite quad LNB

Rev. 1 — 10 June 2015

Product data sheet

1. General description

The TFF1044HN is a 10.70 GHz to 12.75 GHz K_uband down converter for use in

universal quad and quattro Low Noise Block (LNB) in satellite receiver systems. The

device features two RF inputs (two polarizations) and four IF outputs (up to 4 active IF

paths). It integrates bias generation and control for the required external LNA stages,

image rejection filtering, LO generation, down-conversion mixers, IF amplifier stages,

voltage and tone detection on each IF output (for polarization and band selection) and the

4 (IF channels)  4 (2 polarizations, 2 bands) IF matrix switch. For flexibility, the gain can

be controlled in three discrete stages, the polarization of the RF inputs can be swapped

and the second stage LNA biasing control can be switched from pHEMT to BJT

configuration.

2. Features and benefits

 Low current consumption integrated pre-amplifier, mixer, buffer amplifier and

PLL synthesizer

 Integrated pHEMT/BJT bias control for external LNAs

 Flat gain over frequency

 Single 5 V supply pin

 Operates with a low cost 25 MHz crystal

 Crystal-controlled LO frequency generation, alignment free concept

 Dual simultaneously operating LO frequencies (9.75 GHz and 10.6 GHz)

 Adjustable step gain (30 dB, 33 dB and 36 dB)

 Integrated switch matrix

 Integrated voltage and tone detector

 Low phase noise

 Low spurious

 Low external component count

 Alignment-free concept

 36-terminal leadless plastic thermally enhanced very thin profile land grid array

package 5.0 mm  5.0 mm  0.72 mm

3. Applications

 Quad LNBs

 Quattro LNBs

 IP LNBs
